Looking to get my mk5 gti stage 1 tuned, I already have a k&n panel filter fitted in the standard air intake. However, would it be advisable to upgrade to a cold air intake (ramair in mind) before the tune? :thinking:
Thanks!

IMO, save you money and put it towards a downpipe, if you don't have one already.
-
I would recommend checking the DV, PCV and hpfp cam follower before remapping to ensure good health. Also consider doing a precat delete to flow better / lower EGT / spool quicker. Panel filter won't hurt and I think you will be very pleasantly surprised with the gains from stage 1!
-
Yep, got to agree.
A 3" downpipe (ideally full turbo back exhaust) with a decat or sport cat is the best bang for buck on a TFSI in terms of hardware upgrades.
I'd put an uprated fuel pump and uprated intercooler before an intake kit too.
The ideal scenario is deciding now how far you want to take the power, get all the mods, then fit and map in one go.

Yep, the big 3 are HPFP, intercooler and downpipe/exhaust.

Neither, buy a s/h hpfp instead and an S3 intercooler, useful things.
Or upgrade your brakes instead. :driver:

I wouldn't butcher the OE exhaust, get a downpipe if you must. Standard filter is fine and the DV, PCV & HPFP are all solid proposals.
With a full TB exhaust on a Revo stage 1 map at least you'll probably get a CEL light up. Stage 2 map eradicates this problem. At stage 1 a cat-back system will give you less bother I expect. :happy2:

Agreed. I decatted my OEM downpipe and noticed nothing, other than a tinny blowing noise because the wall thickness of the cat carcass is so thin. As well as that, the way the OEM DP necks down to 2.5" abruptly isn't pleasant for flow.
I went for an APR downpipe, which is much thicker cast steel. Milltek offer something identical to that now, so obviously they found the same Chinese foundary and did a deal :grin: The result of the cast elbow is a really refined tone. No nasty blowing type noises, just enhances the tone of the factory exaust really nicely, and improves flow no end being 3" ID all the way through to where it joins the factory exhaust.
An intake can liberate as much as 30hp at the top end at Stage 2+ levels, with no loss of bottom end......but you need to spend £450 on the VWR intake to get that kind of gain....and it fits like an arse. Rubs on things, knocks coolant elbows off etc. The Revo intake probably sees similar gains, but it's very noisy.
The factory airbox needs pressure testing ideally, just to see how much of a pressure drop there is. If it's less than 0.1 bar, I wouldn't worry about it personally.

Sorry to hijack here, but do you mean a Second Hand HPFP? If so are we talking a second hand Autotech/etc or second hand from say an oe S3?
This thread is exactly where I am at with mine so very interesting read so far!
Thanks in advance!!

The pumps on the k04 cars are the same as on k03 cars, so there'd be no advantage to it.
But a second hand Loba, APR etc, is definitely a good idea.

Awesome! Thanks for the help, it's been an interesting read and a learning curve to say the least. :notworthy:

Learning indeed. I wish they'd done "How cars work and how to modify them" at school instead of Geography and PE.
