    tuning advice or 2010 Silerado 4.3

    anyone have any tuning advice. didnt get much help in the V6 section.
    Im used to using a Predator so this is all pretty new to me and a lot more complicated. I don't understand what a lot of the tables mean. I'm not trying to build a race truck "right now", but want to tune for my 22" tires,wheels, and make it get the most out of what I have. I plan to add a CAI, and maybe an aftermarket exhaust if I can find one but I just want it to shift good and hard and have better passing power and throttle response. I will throw in a big block when Im ready for that.
    I have the BETA software so some tables may be different.

    Wow I didn't know they were still putting 4.3s in trucks. Cool.

    I don't know how different the PCM is in a 2010. But the ls1 pcms are different then my 98 4.3 Jimmy's PCM and I found this right up very useful. http://www.ls1gto.com/forums/showthread.php?t=356667

    thanks, I kinda gave up getting any help on here.
    Ive been just tweeking a little at a time. The tranny feels pretty good now but I have my 17's back on.

    I wish they would have put the new 3.6 and 6 speed tranny like Ford did.
    They put the new Mustang 3.7 in with a 6 speed. over 300HP and better mpg.
    19 avg and 23 HWY.
    the 4.3 is proven bullet proof though.
