I was there where were you????? Where to start? According to hypertech
www.hypertech.com. Their dyno on a 07CC aisin 268hp stock. Mine with the egr unplugged was 281hp, then I deleted the DPF and now it's 296hp.
The difference between their stock 268hp and stage 3 MAX hp 367 = 99hp
The difference between mine stock 296hp and stage 3 MAX hp 373 = 77hp where's my other 22hp?
I started with 29hp more but only end up with only 6hp more????? I talked to hypertech and they don't know why??? Where's my other 23hp. Not to mention they claim +129hp on stage 3, well thats the "DIFFERENCE" on their truck at a certain rpm.
I haven't noticed any real (maybe 1mpg) gains in MPG either.
