1G car feels weak at full boost

[Stizzyflip611]

i just recently installed an aeromotive afpr and ss lines. i adjusted the fuel pressure accordingly with the vaccum line disconnected and i started up the car and it idles great. i go and take my car out for a drive and it starts to hit full boost and it feels sooooo weak, like i hit a ####in wall of pillows. do i have a boost leak somewhere, can this possibly be fuel cut?

a little side question. do i need the bracket that is connected to the 2 right side mounting bolts of the throttle body and the cam angle sensor??

thanx alot.

i have a 92 laser awd 5sp. walbro 255, the afpr and ss lines, balance shafts removed, act 2600 w/ street disc, etc.... the rest is in my profile.

thanx again

Give us more info like boost reading in relations with rpm....etc. The more info the better.

Yes, that's the TB stay. It's there to support the weight of the TB, elbow and uicp.

the turbo spools up like it always has, im at full 12-13 psi by approx 3100 rpms and it holds, but it doesnt pull like it did before the afpr install. i will try doin a boost leak test asap.

also im still on stock injectors and stock exhaust, not sure if that will help. both soon to be changed.

thanx

I do a leak test every time I touch the intake side.
What's the base pressure setting with the vacuum off?

 

[Stizzyflip611]

37 psi

37 psi

37 is right. Did you touch anything else? Did you check for fuel leaks using the check valve? Double check the base setting? Does the car sputter? Maybe your butt dyno is broken?

BTW I use to see this girl in Howell right across rt9 from the Pepboys.

 

[Stizzyflip611]

butt dyno???? huh

no fuel leaks, cuz i run the car and i cant smell any fuel at idle.

im gonna cheeck for boost leaks in a couple days, maybe thats it...

thanx again


oh wut gurl across from pepboys
