I noticed that my intake pressure never goes below -30 anymore and it stays around -70 under hard driving (throttle @ 100%) by the way this is a NA motor. On my friends car (NA also) his VAFC intake pressure reading goes all the way down to 0.00. So I called a shop to see if they could help me out and they said the reading should be at 0.00 under hard driving. The only thing is, they dont know why I cant go to zero.

I tried changing intake setups. But it didnt help any...

Do any of you guys out there know how to fix this problem? If so please help me out. Thanks

 

Anyone???

Well I think it might be that I have a bad MAP sensor...
