How far can a custom map take an otherwise bog standard Ed30?

(1/5) > >>

Rayhoop:
So I've been searching the forum and reading lots about remaps etc.
I have not found an example where an owner of a standard GTI or Edition30 has a custom remap on an otherwise standard car.

What I was looking to find out, was how far can the standard car be mapped before breathing, intercooling, fuel supply becomes an issue.  when I say "how far", I mean a nice smooth and strong map - not something that has a spike of high power at one point but everywhere else it is wobbly.

I understand there is a good reason why most people will combine a set of mods before investing in the remap - but I'm just curious if anyone can give me actual results along the lines of:

without other mods, we mapped it too xxxhp
sorting out the intake then tweaking the map resulted in a xxhp gain
exhaust + tweak = xxhp gain
hpfp + tweak = xx...  You get the idea.

Can anyone provide any insight into what they found?

MC71:
Stage 1 is as much as you'll get from a standard car otherwise they'd be no need for a low cell cat (or cat delete), a CAI, a bigger cooler or a HPFP to get any more from it. It's all about the flow and that'll be restricted without the supporting mods.

Not sure whether you have K03 or K04 but contact one of the custom tuners to see what's what. Niki at R-Tech for a custom linear map IMHO or a generic linear map from REVO are your best bets.

Loads of threads on every Level of map and what you'll achieve, even a thread on Dyno results, all in the Performance section.

Happy modding!  :happy2:

On my K03 GTI I got 248.3bhp from stage one custom (r-tech), panel filter and pre-cat removed. R-Tech's mapping techniques have moved on since then and more power and torque is available from those mods  :happy2: I couldn't speak for other tuners, I don't think they have investigated new techniques (certainly not heard about it on the forum)

Typically outputs vary dependant on condition of your engine and anciliarry components (these TFSI's mostly have 60+k miles now) and what hardware you choose.

Have a read through this to get a flavour of what different branded mods do for the output and curve:

Rtech is the place to go.

My GTI  (k03) made 267bhp and 324lbs ft with just a intake  :happy2:

Rayhoop:
Good stuff.
I hear a lot of good things about R-Tech.  Might have to give them a call to find out what can be done.  But... before I do that - off to the dyno thread to see if I can get an idea of what is possible!
