Anyone had any luck with the edge evolution for the nnbs trucks with the 5.3? I know everyone will agree that custom tunes are the way to go, but I just want something that I can take out when it goes in the shop. THANKS!

 

I don't have the 5.3, I have the Vmax 6.0 with 3.73's. I have the Edge Evolution and it's ok. It will suffice until my warranty expires, then I will get a "real" tune. It definitely helped.

 

Look at HPtuners ----------------------->>>>

 

You can flash back to your original setings with HP Tuners.............

 

EFI live too. Tuning yourself is the best way to go if you have interest in learning it.
