i just intsalled a boost gauge, A/F ratio gauge, 1G blow off valve, and some custom IC piping on my 2g AWD. it idles and revs fine and the gauges seem to be working fine, but when i get on it and the turbo spools it bogs down and throws a check engine light that comes on and goes off real quick. it's not a misfire, and i dont think it's a boost leak. is there anything i could've done when i tapped the fuel preasure regulator or spliced in the wires for the AF gauge to the ECU? thanx!

Hey I have had the same problem with mine. After coming down from a high rev, the revs drop to like 0 and jumps back up. The car cuts off for a second and turns back on...I think I might have a leak but am unsure, ill keep checking back on this, let me know if you fix it.

 

is the blow off valve going back into the intake?

 

sounds like a boost leak to me.. if it only does it when your getting into boost its going to make the cars mixture rich as hell and its going to act funny.. check to make sure its not a boost leak

 

it's venting back to the intake. i'm going to re check all the piping today. hopefully it's something simple. but i dont think it'll throw a CEL if i have a boost leak. i'm going to double check the wires going to the ECU also.

 

oh, and chris, are you venting to the atmosphere or back to the intake?

 

Yes it is going back into the intake...

 

im going to be a PITA and ask how did you wire your AF guage in
