After two weeks and $1200, I got my car back. And I'm pissed. I still have the same problem. I bought a 190lph fuel pump, and when the car hits full boost, the car hiccups, the RPM's won't go up AT ALL, I can't gain ANY speed. I tried but i stopped b/c i didn't want to blow anything up. they didn't install the boost gauge like I asked them too, but I turned the boost down anyways. Could I have a boost leak? I still have the stock blow off valve...could that be the problem? I need help badly.

 

did you change the injectors?

 

Just hook up the boost guage yourself. Its extremely easy. Go to www.vfaq.com I dont think that the injectors will have much to do with it. Those should be fine. And if it was a boost leak you'd have more problems at low rpms as well, like around idle. Make sure that the MBC is hooked up correctly. Pics would be helpful

 

no. they are next on the list to buy. some 580ccs, afcII, greddy bov, and a fuel pressure regulator. Im sure one of these parts would fix my problem. Im very frustrated because I could of bought all these things but I had to pay an outragous bill pretty much just to get the interior lights working, b/c some dumbass who had the car before me cut out the cd changer and left the wires exposed and melted the whole rear body harness.

I was calling looking for a dyno, I was talking to this guy and he just gave me this whole lecture on turbos and whatnot.
He tried to explain to me that I might need to upgrade my wastegate also, but I really wasnt understanding. If someone could explain simply what it is and what it does I would appreciate it very much.

 

I don't think you need a new FPR with the 190lph pump.

 

you shouldt need one

 

true. i think its only for the 255.

 

don't rule out a faulty install of the fuel pump. the grommet is very easy to tear.

 

If it was doing this BEFORE the fuel pump install I don't think the new one is the problem. I also don't think the wastegate is your problem either. Check all your intercooler hoses and make sure the clamps are tight. check vac lines for breaks and tears.

 

The stock 2G bypass valves are leaky. I am selling a Greddy Type-S BOV if you are interested
