im looking for a tuner for my 04 lb7. All it has for mods is a 4inch mbrp straight pipe. Im looking at the Diablosport predator and the Quadzilla Stealth 2 race. Im looking for mostly some smoke and power but dont want to blow my tranny. Im planning on doing my trans in the future and getting efi live. So right just now im just looking to buy a cheap tuner so my im looking to see what is the best of the 2 and wont screw up my truck

 

better off getting efi now and updating tunes later. off the shelf tuners or programmers are garbage in my opinion

 

2x

I had the Diablo runner on my truck before I got efi live and it was night and day different. You can tell your runner that you want it to be "tranny safe" and the when you get a built transmission you can update the tune.

save the money and do it once.

 

i like the ppe tuners
