Another Boost Issue Thread

[Biohazed]

OK as the title states I am having boost issues with the GTP. Been battling this since I got it .. Changed the BBV, all new Vac Lines, and Last week changed out the Fuel Pressure Regulator ... after that I had 8PSI constant ... that lasted for 2 days ... now sometimes I can get full boost but only very occasionally... Usually is putting out about 3 psi ... On my Mechanical Boost gauge, at idle I'm reading 20 inHG steady so It definatly does not seem like a Vac leak. so I'm really at a loss at this point. any help would be very appreciated.

Belt slip?

[Biohazed]

Tensioner seems fine, no glazing, noise or any other signs of belt slippage, oh and if it helps it has a Stock pulley still, I havea 3.4 MPS but it hasn't made its way onto it yet, lol

[JoshsGTP]

Have you tried a new belt?

[JoshsGTP]

I about **** my pants trying to get a new belt on so they do fit tight.

[Biohazed]

belt on it only has maybe 2000 miles on it and is in great shape still.

Did you tighten the adjustment nuts on the BBV all the way? May have slipped and not closing the butterfly all the way.

[Biohazed]

I'll check that tonight, pretty sure I had it tightened tho. whats the possibility its the Boost Solenoid?

You say you replaced the BBV.. which is a part we don't have, so I'm not 100% sure if you replaced the black can looking item the Actuator or the little electrical Soleniod.

Typically I've noted the soleniod being bad and causing this kind of issue

i replaced the Black can looking thing :P ordered a Solenoid today will have it tomorrow hope this fixes it ./... tired of this thing not boosting right .. lol
