I just picked up an '06 QCLB 6 spd. lonestar edition with 200,000. I would really like to make some more power. It's my towing rig and runs like a champ the way it is, i'm just ready for some more. What are your suggestions??

 

Gauges, cold air intake, 4" turbo back exhaust.

EFILiVE programmer.

That will be enough power to blow the trans if you don't keep your foot out of it.

 

I agree with the above post. Anarchy does great tunes and excellent customer service. there are several other companies that do It, i just chose anarchy so i can post on their results. ive read that with a modded tranny, but otherwise stock truck, their tune ran 520 somethin hp on a dyno.
