Scan from 13.3 run!Input pls

[Bio248]

okay, got your PM. you must have really wanted me to check out this scan for you.

here is my diagnosis, which may not even be a very good one since i dont really do my own tuning, i just scan and tweak my AFC if needed..

- your IPWs look fine, youre in the 19s which is still very safe. this means you arent running out of fuel.
- youre still knocking a bunch even when youre rich as crap. this means you probably should try pulleying up on the blower. try a 3.4 and see what kind of timing you can run as well as how much knock you will get. you want to lean it out more to about 11.5:1 when youre WOT.
- your fuel trims lock in at zero when you go WOT, so for you right now i think that is the best youre going to get with what youve got going on right now.

my suggestion:

depending upon how cold it is down there, which it must not be because youre still going to the track in december..you might be making more boost than usual. if i cared about it enough, i would pulley up in the winter because i knock just that much more because of the cold air. i think you should try going back up a pulley size or two and see what you can get out of it because it looks as though you are still running stock timing (13-14* WOT timing with a little knock = stock timing?). youre going to be much better off running 18* of timing and a bigger pulley.

start there and take a few more scans after you tune in the new pulley. tell us about it and we will point you in the right direction.

The tune started as a DHP 1.0 bin file. All we did is added the 85mm maf bin., 160* t-stat, and raised the shift points. Ran the table modifier a couple of times to get the LTFT' in line. I spun a rod bearing two weeks ago and had to install a used 2002 motor. So after that we have not had to much time to work on the tune. I am thinking it is something else besides the tune. (Valve train, sway bar, etc.) and i still have the stock mufflers and its not really a 3" down pipe it is the flex tube that comes with the headers.Timing is stock and we did try the 3.4 pulley at the track and the Kr went down 1* that is it. We were going to add some race gas but i was running that night with 3/4 of a tank of gas.
