I recently bought a 2009 Silverado 1500 4x4 with a 4.8L SFI engine, I also just ordered an K&N cold air intake kit. What I'm looking for now is a good performance chip to install but not sure which one would be best recommend my truck.

Any thoughts?

Thanks

 

ive been pondering same question for for years now on 2006 1/2 2 wheel drive silverado. its not really a chip . it is a reprogrammer. diablo,bully dog super chip.

 

Blackbearperformance, gowheatley, Nelson tuning, or a local tuner who has a good rep. These are custom tuners for chevy trucks, I ran a Wheatley tune for years with no complaints at all, now I have a buddy of mine tune it locally. Had a bullydog, hypertech, and edge before that. Shouldve went straight to a custom tune. Was well worth it, had way better gains than a out of the box programmer

 

Thanks for the info. I do appreciate it.
