Hey All, I need to ask for some help.
I'm getting really strange boost when feathering the throttle in 1st & 2nd
Boost kicks in and raises to 0-2psi, the car pulls and then holds back, boost drops to -30vac... On hard acceleration I get 15 and then drops to 10psi holding steady... But doesn't feel like the boost is actually making a difference
Could this be the N75 valve or the MAF... Would it be worth replacing with an upgraded valve or a manual boost controller?
Also what boost should I expect as standard
Cheers in advance
Al
