Picked up my first golf gti today 55 plate and I'm very pleased so far , but going to remap it as I feel it needs more punch was going to AMD they say can take it to 265 bhp anyone else had their gti remapped by them? If so was you happy with the outcome ?
-
I run an AmD Tuning custom remap with 265bhp, but I have additional modifications to get that power. They are;
Milltek cat-back stainless steel exhaust
Panel filter (K&N)
GFB DV+ diverter valve upgrade
My girlfriend has almost identical mods but only gets 259bhp, which I like reminding her about. The power gain varies with everyengine, my advice is expect 230bhp with just a map and up to 250bhp with mods then you won't be disappointed.
The AmD map, for me, has been perfect for nearly a year and 8000 miles. They have gotten better in recent times, and they're customer service is pretty good.
-
Also, check out the guides on here for checking the PCV (pressure control valve) and high pressure fuel pump (HPFP) can follower. AmD do scan the ECU for faults and check the car over, but they're worth checking yourself ASAP.
Sometimes a GTI has a broken diverter valve which puts then seriously down on power, so before a remap check that too, plenty of info if you use the search feature.

Very good advice about Diverter valve my car felt sluggish so checked the Dv and rubber diaphram was ripped badly, £42 to replace and its like a different car afterwards
No Remap needed on them but thats just my oppinion, 200bhp is more than enough on a fwd car especially wit no fancy Differential to help out on them either!
-
An estimate of power loss is about 30bhp and similar tourque loss so well worth checking. I got lucky with mine...
-
I've done my home work on the gti , I've been in the motor trade for 21 years and I am a fully qualified mercedes-benz technician, so I know my way around cars and this forum has been a great help already.
I've already brought cambelt kit and water pump doing that in the week and also the cam follower for the fuel pump , been reluctant to use the car at the moment until I've done these little jobs then I will set about doing the other bits ,like the diverter valve and PVC valve plus a full service also has outstanding recall on the coil packs which is a result .
-
Sorry text mistake pcv valve
-
also on the early gti--they suffered from noisy cam chains and warn followers
-
Being a mechanic you'll have no issues then. Space is a bit tight for the DV on a K03 engine but you'll probably be lucky enough to have a ramp... Lucky... Where about in Essex or Kent do you hale from then? There's usually a regular monthly meet at Lakeside with a load of us from this forum.

I live in Dartford and work at mercedes-benz lakeside

265bhp from that setup isn't possible matey :sad1:
A realistic 240bhp from that setup car is what you can expect. The cat back exhaust doesn't add much power, although the panel filter will give around 5bhp.
AMD's dyno has been known to be generous, a guy (TomGTI maybe) had an AMD map and dyno run and went away with 260bhp, then he went to JKM dyno day and got 240bhp.
See here for examples of what to expect on proven accurate dyno's:

I have heard the same things, I need to find what dyno AmD use. I'll try and verify my power somewhere reliable one day soon.

Try a Dynodynamics dyno, they are typically accurate. Surrey Rolling road & JKM in Portsmouth have one :happy2:

When you add up the advertised power gains that manufacturers claim their products make, plus a remap;
Remap 40bhp
Exhaust 10bhp
Panel filter 3bhp
Original power 197bhp
Its why I say with a stage 1 package expect 250bhp. Don't think I'm being unrealistic, and did see someone recently on here who put the AmD figures to the test and got a good, close (but not matching) set of figures. But I can't defend my claims as I have no evidence so happy to accept the consensus.
For now... :evilgrin:
-
my 05 GTI made 247 bhp and 307 ft ilbs torques with rtech linear tiv map!
no other mods
would have been 270 bhp on amd rollers

With those mods you may get high 240's, may be even 250bhp. . . But 265bhp (as the OP is expecting) requires an intake or a Downpipe and sports cat :happy2:
With Stage 1 R-Tech, pre-cat delete and panel filter I got 248bhp at R-tech and 241bhp at JKM. Typically all stage 1 cars either stock or with the panel filter / pre-cat get around 240-250bhp. Without aiding the flow or air either into or out of the engine, that's about all that is safely possible from these. . .
Would be helpful if Niki was around to explain this :sad1:
-
R tech bloody r tech that's all u hear !!
What's to say there rollers don't add extra bhp and torque figures?????

They are compared against 3 other dyno's on the estate regularly and figures checked against the MAF reading calculation for BHP.
Niki is adamant that his dyno is very accurate.
-
As my comment said, MAX possible is 250bhp but as we all know, those figures from manufacturers have to be taken with a pinch of salt. Regardless, the increase in power after my remap was amazing.
-
Totally agree :happy2:
-
I got 300bhp and just changed the air filter :happy2:

Agree to all of that :happy2:
-
However, until I have proof, I'm still claiming 265bhp. :booty:
I am prepared to admit my wrongs if its proven to be nearer 250bhp though.
Back to the OP post, have you considered Revo maps? If you're running no mods then they may be better and cheaper, plus the SPS feature is really cool.
-
The SPS switch is a MUST if you go Revo IMHO

Oooh dear don't dare question R-Tech,this place is fanboy central for them :grin:

Just like UKiv and golfgti forums :grin:, when people go to R-Tech they come back pleased as punch after getting a great map, great banter, an explanation as to what has been done and an issues highlighted all for a lot less than the mainstream tuners. . .
I guess that's why they always get so much praise and many recommendations :happy2:
-
I've not had any problems with amd very happy with the service the provided,
Car runs fine, does more mpg as he said
Of course they added a few extra horses on the print out but hey mans got to pay bills too :signLOL:
-
Right on cue :happy2:

A custom remap from any experienced garage will always be better than "off the shelf" types, but only see a real benefit when other mods are applied as the map written can be tweaked to account for individual variations in air flow, fueling and engine condition.
But the Revo maps are tried and tested, with the SPS allowing for running stock, performance and security modes is seriously good value when you consider how cheap the thing is.
-
Pardon my stupidity but whats SPS?
Whats the going rate for revo stage 1 out of interest and why they better suited to otherwise standard motors?
-

In short, it allows you to switch between different engine maps, like the different modes in higher spec class. It means you can run the car "stock" during the week, but then up the power at weekends or track days. It has an added bonus of a security mode, which disables the engine until you choose a different mode, so even if someone got your keys, with the SPS they can't start the car.
Revo maps cost around half a custom map (£200-250 I believe). They're slightly better for unmodified cars as they're based on stock engines, but this isn't to say they can't be used effectively for modified engines. The problem for a company like Revo, is there's an almost infinite number of modification combinations that they have to write their maps to cope with, and this is where a custom map is better as it's unique to each engines.
I'm no expert, so if you're seriously considering something like it talk to R-Tech, AmD or any other top garage for better advice.

Revo Remaps cost around £500, and the SPS switch is around £150. The SPS really is a must, as disconnecting the cars battery will lose the Revo settings . The SPS is the only way to restore the settings (without a trip to your Revo dealer).
Revo will have written their maps using one of the mainstream suppliers (Milltek for exhausts for sure, couldn't guess which for intake. .), although will work fine with all other mods, it woulds best with the mods the map was written to.
I don't see how Revo would necessarily be better for a un-modified car? Revo wrote their maps when the GTI was new when all engines and components where clean and working correctly. As these cars are getting older and components are wearing or getting covered with Carbon, a generic map is treating it like new (ie asking for the full fuel pressure, where a sighting tired pump will struggle).
A tuner tweaking a map for your exact car will pick up on things like tired fuel pumps, MAF sensors not reading right, lambda sensors giving odd readings etc. . .
Tuning has moved on recently, where R-Tech have identified extra features to improve power delivery and figures (TIV mapping is an example of this). I'm not sure if other tuners are constantly developing their maps? With the fact that the mainstream tuners seem to be focussing on the latest models (mk7 GTI & R for example), I doubt they are too bothered about further improving the maps for the older models like the mk5. . .
Which ever way you go, either Revo or R-Tech remap will put a grin on your face :drinking:

r tech all day long coz they are brilliant
:signLOL:

Didn'tknow that about the development of Revo software, I stand corrected! I was considering Revo stage 2 anyway for reasons already discussed.
End of the day: Remap = Win all round.
