    I just bought a 2002 Ford Taurus Id love to be able to TURBOCHARGE and tune. Maybe OLSD 3bar?
    It only has 155hp, and it would take some boost to get to 400hp. I have attached the tune, and some...

    Cant you pull fuses for ABS/Stabilitrac when your at the track?

    If your ECM is like most others, even when you press and hold the button, some stabilitrac is still there.

    I couldnt load the tune now, but also dont forget to max ALL the tables under Engine Diagnostics, General, P0068.

    This will keep the limp mode problem from happening when you up the boost. If you...

    Also put the correct idle value in the first cell of the MAF curve, it will still use that one to try and start til MAF fails.

    Did you scale the pressure shift areas in the tune as well. EX: Take value in the shift pressure areas by gear at 500ft/lbs and move to 250ft/lbs as your tune is scaled by 1/2, you need to move the...

    If the ECM is an E40 from an LS2, then your better off with a 411 ecm IMO. Look at a 03-06 silverado harness and pcm.

    Go to at least a 7series NGK plug, a 6 is NA territory for high compression LS2. This will lower EGT's and help with KR some. If your goona really lean on it may even need to go colder down the road...

    Multiply your higher MAF tables by the % lean. So if your going WOT ~8000hz, then from 8000hz on up, multiply by the same amount. Example, your seeing WOT AFR of 13.5 and you want 12.5. Take...

    If that was a warm startup, it looks like a big vacuum leak to me. Unless you have a MONSTER cam.

    It starts up rich, then goes dead lean, look at your O2 mv and your MAP values. Shouldnt be...
