    Yes, but I might do one more just so we have more feedback. Shoot me an e-mail when you're ready to test.

    The first dymo was alittle misleading with the trans lockup squigly :-)
    THis is the first madtuner tune!
    Ill let you guys be the judge remember my car was already modded
    with the first dyno and i was told to expect little to no gain in HP
    so far i am very happy with the trans shifts at higher rpms limiter is gone
    but you didnt hear it from me LOL!! and gas mileage is up alittle,we get this air/fuel dialed in
    and we are done

    ezed1 thank you for all your help with the R&D on the 2007 ESCM or lack thereof rather.

    His car is actually a 2007 running a different engine management system than the 2005-2006s (random/abundant knock retard is not an issue on these ECMs).

    One thing that can be said about 2000+ Northstars is that they are very consistent in horsepower between runs. They'd make good bracket racing cars.

    The pretune dyno graph wasn't accurate if you look where the little squiggly is it throws off the numbers. Without the squiggly the numbers were about the same in the 260 range

    No take a look above. It's 271 vs 264 hp. Pretune listed shows 271 tuned shows 264.

    Post 50 vs 51.

    What ezed1 meant is that his first graph was inaccurate. You have to look at the right part of the graph where the engine actually should peak horsepower. The peak that you see around 95 MPH (causing the horsepower spike to 271) was most likely his torque converter locking up. His car has some modifications already which is why he has more horsepower than a stock STS. Corrected air/fuel ratio and increased timing on his car didn't make much of a difference in terms of horsepower.
