    Tune for Turbocharged Z28

    Hello,

    After researching topic after topic and getting nowhere, I decided to post it up on the forums for others to evaluate my tune. Unfortunately I dont have wideband tuning capabilities so that is not an option for me. I am pretty sure I am struggling with injector data somewhere. Here are the important details:

    Car:
    -2000 Camaro z28 6-speed
    -Modifications: t76 Turbo (7-9 lbs of boost), hot cam, ls6 intake manifold, exhaust, 60 lb injectors, 2 bar tune (I now use SD)
    -Ran fine BEFORE the turbo and injector install, received a mail order tune from Frost

    Problems:
    -Car surges while driving
    -Car wants to die when trying to return to idle (and usually does!)
    -Seems to be running very rich

    Thanks in advance for your help!

    Dave

    Not having a wideband is not an option. You MUST get one or take it to a tuner. Are you running a boost referanced fuel pressure regulator?

    So you are running a manifold referanced regulator, same as boost referanced. I suggest buying the bannish dvd and an ngk afx. The dvd will have the correct injector data for you and instructions on how to tune it. Ngk afx is a good all round wideband, if you want to do it yourself you will need it.
