Hello everyone, my name is Braden and I recently bought a 2001 LB7 ext cab 2500HD. So far I have done a Pro Flo 4" turbo-back exhaust, Inglewood (Mike L) trans cooler and a K&N intake system. I have been looking into a PPE boost valve and a tuner. (mainly EFI Live) I have heard many good things about the EFI tuner and many negative about the other such as Bully Dog, but to each their own. Any tips, opinions, facts etc. would be greatly appreciated. Just FYI, I am not looking to drag race the truck or do anything crazy, I just want a bit more RELIABLE AND SAFE power and a little bit more smoke would be nice..good smoke though, I know that smoke is generally the sign of a problem such as high EGTs or rich/lean fuel/air mix. I also know that someone is bound to think "if you bought a diesel to blow smoke, go return it", I didnt buy my truck to blow smoke at old ladies all day lol I just would like for it to roll coal when I want it to here and there, just like a diesel should. (in my opinion). Once again, any tips or advice would be awesome!
