    ok so here a log from tonight, i didn't tonight the shifter had dropped (i think my bracket for the shift cable needs adjustment) must have touched the tv lever.

    anyway if you jump to 17:11:33 i got on it and it stumbled, in tune v4 i added more fuel and pushed up rail psi a touch. the stutter didn't change much if any i may try some other tunes i have but when i hit it hard the boost limit fueling dropped then came back. with that said would it be a good idea to raise up the boost limit table where it comes in? other than that it droves nice pulls great, egt's went up a bit due to the fuel but i will go back to v3 tomorrow.

    Try reducing pilot timing, the 03-04 trucks don?t like extra fueling with how the aggressive the pilot timing is.

    ok so i ended up changing my base fueling to come in 100% and 2000 rpm and up, also torque limit 1800 and up. i think my stutter was rail psi not being there when i hit it. i ran it this morning and works very nice still clean and i added some more fuel up top and let the boost limiter out some more in the mid-range. this tune drives nice egts 1250+ on the hammer so i will cap the fuel there i think.

    i made a few more timing changes based off a calculator but have not ran them yet. for now, this will be my daily tune overall very happy thank you again Jim
