Hey folks, New Gm owner and poster here. Can't figure which is better or right for me.. My setup is 07 silverado 1500 with 4.8 and 4 speed a/t. Daily driver and lite weekend towing. Looking to get a little more power and firmer shifts, hit the sluggish feeling of it. It has a k&n cai and magnaflow plus duals, no headers.. I plan or getting a custom tune from nelson or a hand held programmer but unsure of which. Also plan on doing the servo swap. Thanks for any help!

 

get it tuned , programmers shouldn't even cross ur mind bro they suck lol

Dang that was quick.

 

Yeah get it custom tuned, don't waste your money on a hand held. Use one of the sponsors to the right, I used Black Bear and I'm very happy. Several choices though and they are all good.
