    Try setting B3609 to zeros.

    You need at least 70% throttle to get PE, is TPS indicating better than 70%...?

    thanks joe, i tryed that. that didnt help.i am getting to 100% throttle, still,, you have to make 3 pulls til it goes into pe. it does that on the street too. you can feel a differance in the truck when the pe goes in.
    i remember reading on the hp forum that there was something with the 2006 trucks that prevented them from going into pe to save fuel. i have tuned other years silverados , they never seemed to have a problem getting into pe with a tune like this ??? im stumped.

    I can't see anything in the tune file that would prevent it.

    Try setting tables B3644, B3645 to about 1.3 or higher and also try lowering B3616 to 50% or lower.......

    Are you getting any knock/pinging at WOT? Your B3618 (TO ME) is scary "LEAN"......

    thanks guys. i'll give that stuff a try. im not sure i understand how B3644 works, my thinking was that it is the time in secs that the pe transfered in ?? org tune it was .1
    i am not getting any pinging at wot. i set B3618 to that value as a test, because when the truck does go into pe, after the 3rd pull,, it was at 10.8 for fuel on the wide band, i tryed to cheat it to go leaner.

    ok, i tryed that. it seems to go into pe, but not when it should. why wont it go into pe when the throttle gets past 50 %, it takes like 3 secs or more at wot before it finally goes into pe ?? i know im missing something

    Have you tried messing around with the Traction Control tables? Also, try disabling the B0701 CatOvertempertature(COT)....When enabled, it richens up the mixture(quite-a-bit) to protect the Cats...especially at WOT!!!!!

    Can you post up some Data Logs? Kinda hard to help with no data logs to view........
