power loss

[suprasport91]

I just bought a 60-1 upgraded turbo and installed it recently, although there is a little bit more lag than the stock turbo it pulls hard.

Now for the problem; in first gear ( A/t) i am at about 10 psi...and i can feel it, however, when it shifts to 2nd, i can feel a loos of power and my guage is now reading about 6 psi.

Other issues: Idle is a bit rough, as it idles at about 550-600, dips and sometimes stalls on upwards gardients; I backfire occasionally at high rpms ( 10-12 psi) .

Any help will be greatly apreciated, thank you

did you mess with your timing? If so, check it & make sure all of your I/C piping is tight. Does the 60-1 rock?

yeah its awesome, it was beautiful when i recieved it, almost didnt want to use it....that idea didnt last long though, i didnt mess with timing, and im pretty sure all my piping is on pretty good, ill check but im almost positive its on there good.

Also i think i may benefit from reseting the ecu. Are there any possible issues...

You got your BOV vented to the atmosphere? I have a SSQV and the car would stall out at idle going up a grade...eventually the ECU "re-learned" and it happens very rarely now.

Have you checked for codes?

 

[suprasport91]

i have checked codes, only thing that comes up is when i backfire, thats all

 

[suprasport91]

and i do have a a vented ssqv, ill reset my ecu later on, then ill post the outcome, however, although that may affect my stall to a degree i still have an issue with power loss when the car changes gears at WOT

Have you adjusted it? I had to tighten mine down a bit to stop it from releasing pressure too fast.

 

[suprasport91]

i have the newer ssqv, i dont know how to adjust it, i was fimiliar wiht the older model and it had a screw, this one has nothing...

 

[GrimJack]

The new model doesn't adjust. Too many people were mucking it up, so HKS set it from the factory to work on the widest range of setups possible and removed the adjustment.

 

[suprasport91]

widest range my ass, i get pretty bad compressor surge at low boost if i dont ease of really lightly, anyways im gonna check my car today, for leaks mostly, but im gonna reset the ecu also nd see what happens
