    Default 2009 Silverado Question need more power

    I just bought a 09 silverado 5.3 flex fuel and I am looking for a programmer, I have the exhaust already on and the kn filter kit. Does anyone know which one is best performance for the money I was reading some good reviews on diablo sport but not sure. Also anyone know any suspesion performance parts like sway bar, I am putting a 3 or 4.5 lift but thats not for a good while. Thanks to all replies.

    I had a Hypertech Power programmer in my 2000 GMC and it worked great. It gave me plenty power and all the options that I wanted. Hope this helps,good luck and keep us posted.
    [/SIGPIC]07 Silverado LS factory 20's, spray in bedliner, in-bed cargo managment system, matching tint on front windows, K&N CAI, and Hypertech Max Engery Tuner and yet even more mods to come.

    Ya but for more power I would go with a tuner or go with a new cpu. There's pros and cons with both. Ask your frinds if thay have a tuner in there truck 07-09 and ask if you can try it for a day or two
