Stage 1 Re-Map, should I buy and fit a filter first?

[ianv5]

As above:

Car is a standard 2005 GTi and I am thinking of going for a Stage 1 re-map in the near future probably at R-tech. Is it worth me fitting a Forge Twintake before I get the Re-map or after.

If I just get the Twintake and just run that without the re-map will i notice much improvement in performance?

if you're going for a custom remap with R-Tech it would be worthwhile to have the intake fitted first. they'll make sure the map is "prepared" for the better air flow the TwinTake will give the engine.

You would benefit more fitting a sports cat downpipe than an intake. The standard air filter will flow up to about 270bhp to 280bhp and a stage 1 map wouldnt be near that. If you fitted a downpipe you could go straight to stage 2 and have about 260bhp and a more driveable car.

Recommendation for a sports cat downpipe?

Blueflame are doing a full TBE for £675 delivered on a group buy

call them up and speak to Adam and mention it

turbo back exhaust i.e. an entire exhaust system

it can be a tiny bit boomy under load (nothing the radio at a socially acceptable volume doesn't cover) but is totally silent when cruising

for around half the price of a Milltek i'd say it's 100% worth it

Is that the same one as this on the Blueflame website?

Forge, ITG & Evoms intakes have been proven to give an extra 12-15bhp, even when added post remap - see Robin's review. For me, Stg 1 revo gave me 240bhp on JKM's RR, ITG added at a later date, and then (with no map tweaks) it has & will pull 254bhp on JKM's dyno all day any day.

The noise alone is well worth it

Gareth you got some great gains there with the ITG 

Almost tempting me into getting one  but i want some exhaust note first!

to answer to OP's question - Definetely worth getting an air filter BEFORE the map to allow the map to be calibrated for the intake.

R-Tech will do you a good map also

It's as Gareth says. And my review may offer you some additional helpful information:  http://www.mk5golfgti.co.uk/forum/index.php/topic,9988.0.html

....Firstly, Stage 1 is totally "driveable". But perhaps you mean something different than I understand the term 'driveable' to mean.

Secondly, be aware that if, having fitted both high-flow downpipe and air intake and a Stage 2 remap, you will probably find you then need an aftermarket HPFP to avoid cutouts etc. The slippery slope is great fun but starts getting expensive.

Hi Robin, this is where it goes a bit 'grey'! I mean, i am planning to have a Twintake, then full TBE (BCS), then a custom map (1.5) from R-Tech, hoping that i will get perhaps 260bhp, maybe even a bit more, but i am being told conflicting comments reference the HPFP, you for example are suggesting that it is better to have it, others are stating categorically that it's not required unless you are having a Stage 2+ (R-Tech Stage 2)!? I have a Mk V Golf GTi..

All comments welcome, as most confused now!

my understanding was that it's map dependent

if the map isn't requesting more fuel than the pump can deliver then what's the problem? if you're going for a custom map then the tuner should map the car to within the limits of the hardware, right?

[gigolo456]

ahhh, ok, i am hoping then that R-Tech will take into account the fact that i will not have a HPFP and custom the map accordingly!?

....From what I know of Nick, they most certainly will. You are in good hands with someone who knows the 2.0T FSI engine and not in the predicament like someone else who has posted about their disaster.

Have spoken to the Guys at R Tech and have given me great advice. Thanks Ben

Slippery slope is looming but finances will dictate!

Hence will prob go for just the Stage 1 map without filter/downpipe etc first.

Then when I get back from Afghan early next year will spend some of my hard earned on new exhaust, filter, brakes, wheels..............
