I just installed my new 60 mm throttle body and adapter, I am boosting less now, is that normal?

did you seal between the tb and adapter? sounds like you are leaking boost there

i second that notion...

yes. but I did not put a seal between the adapter and the intake minifold, I just out the stock o ring on it....

I know that typicaly when you open up the intake track on FI cars they tend to lose PSI. If it was a small change I would think its normal,a big change I would say its leaking.

 

[Psss]

1-2 psi at the most...

i don't think you should lose 2 psi. i think you are leaking boost some where.. do a boost leak test. could be your cold side pipe, or the adapter/tb.. you shouldn't have to put any kind of sealer on the adapter/IM, thats what that o ring is for. how long did you let the sealent dry for?

10 minutes.

for exmple in third gear it will boost up to 12 then 15 and hold 13-14

 

[srtjay]

are you using an afternarket wga? what were you boosting before the tb?

 

[Psss]

all I have is stage one. before I was boosting 15. but now sometimes I boost 15 and sometimes I boost 12. car is acting kinda of wired

 

[srtjay]

since you are still on the stock wga.the pcm controls how much boost you are running and boost is altered by the weather/climate ..its pretty shitty outside. take that into effect
