s2martyn:
i am at stage 1 with a healthy 258 bhp and ust over 300 torque,(standard was 202 bhp)........i have fitted a 3" intake and downpipe...will i have to  have the map tweaked to get the best results from this????and what can i expect over the 258??cheers martyn

vRS_Pagey:
Firstly where did you get the figures?  258bhp is the expected output with the mods you have but running stage 2 software......

I assume your car is a mk5 GTi?   :popcornsoda:

s2martyn:
yes gti mk5
figures were from r/r at leeds dyno dynamic rollers
i have the graphs here
a friends car on same r/r did 185 stock and 242 after the map,so mine is a little up

vRS_Pagey:
They are very high figures from a stage 1 tbh, but with the additional bolts achieveable.  I have just gone to stage 2 with an Evoms CAI and Milltek 2.75" dp/sports cat, estimated figures from this are 260 bhp.  I'm not chasing figures personally, I'm more interested in the driviblity, and imo its pretty awesome. 
I would recommend having the map tweaked to accomodate the enchancements mate.

Having had my car with the OE downpipe and pre cat removed on a Shark Stage 2+ file I made 252bhp with an intake fitted.  I have now removed the intake and gone back to the OE engine cover but have fitted the HPFP and a BCS turboback exhaust.  As the Stage 2+ file is just short of their stage 3 file which gives about 280 bhp. I would guess that would give me around 260 to 270bhp max. The intake helps with top end power but only by about 10bhp on a K03 from what I have seen on recent graphs. 
From a stage 2 file with the mods you have I would expect the power to be around 260bhp only not as good in the mid range due to the lack of an uprated HPFP.  I will be putting mine on Shark rollers next month to find out exactly what mine is developing, so it will be interesting what power your car makes :happy2:
