boost spike prob??
« on: 11 July 2012, 12:47 »
had my car remaped about month ago once done the car boost at 18psi. since having the car done i have not really gone far in it but yesterday done a 200 mile round trip now the car seems to only boost to 14psi and settles at 12psi.
the weekend i fitted a CAI could this be the prob???

i have agu 1999
no fault codes
checked all pipes cant see any leaks if this helps

I doubt fitting a CAI would do anything unless you havent attached it properly  :tongue:
In all honesty, just check and re check something has obviously changed somewhere - remember boost leaks leak oil  :wink:
ARZ K03s, Oettinger Side Skirts, R32 front, Carbon stage 2, Forge 007p (yellow spring), Forge Actuator (yellow spring), Pipercross panel filter with DSG parts, N249 and N112 deleted, SAI deleted, Carbon canister deleted, Rear wiper deleted, Long Life turbo back custom exhaust with 200 cell sports cat, VR6/G60 clutch kit, Creation Motorsport TIP, Catch can, 'Wellycooler', K04 charge pipe, S3 ported inlet manifold - looks pretty standard on the outside though :)
