    DIABLO SPORT PREDATOR tune

    I installed the Diablo tune in my car. My car is a 2002 z28 A4 with borla cat back , high flow cats slp lid. Does anyone have any ideas about editing the parammeters as far as fuel and spark to make it a little faster.

    do what you can to get your LTFTs all slightly negative. I know you can do some trans tuning. If you can gank torque management that'd be nice. If you can turn off COT, (I believe you can), then do that too.

    Today I adjusted the power enrichment . I decreased it in both RPM power ranges -1% . I took the car out afterwards but didn't notice any differance. I put it back where it was before. Also If I Turn off the COT and torque management is there a chance I will damage the tranny and high flow cats that I just had rebuilt and purchased new.
    Don't get me wrong I did feel a huge increase in power after a couple of installs of the SLP air lid,high flow cats and Diablo tune but I was just thinking that I could get a little more power threw further tuning.

    do like frost said
    turn off torque management,bump up trans line pressure drop shift time.
    if you have cats leave the COT alone.
    you want to drive steady around 1900 rpm on flat ground and set your LTFT to -1,this is the most important thing to do.
    just use the 93 tune or what ever canned tune it has.
    also when you make changes it takes about 75 miles of driving for the computer to relearn

    get some data - check your average ltft's and adjust your injector slope to get your average ltft's in the 0 to -2 range...

    Thanks for the info, I will have my car dyno tuned with in the next couple of months. I think I will leave it up to the dyno guy's for tuning. I don't want to blow up the LS1 yet..
