    That looks like the stock table to me. I change the "C" timing (B0910) table for performance. If you send me your stock file, I'll change it for ya and send it back. You can compare it to your stock tune and run it. PM me if interested.

    due to my high altitude i have logged the baro pressure in the 22.7 range...from my understanding i would then be running in the "A" tables... let me know your email and i'll send you a copy of my tune and the stock tune.

    What kind of timing do you see in the logs?

    My logs show my barometric pressure to be 14.6 which puts me in the (A) table but if I modify the (C) timing table to the point that it would rattle, it does eventhough my barometric pressure is lower than what it calls for to be in the (C) table.

    I use c table regardless of baro. It has worked for me.

    If you are talking timing then look at table B0907 and look at the value. Mine is set to 12.7 so my truck uses this table(C) since my Baro is about 14.2IIRC. I beleive your's is the same since you are pretty much at sea level also.
