Dump the Comp lifters and get the OEM ones instead. That crappy diablo tuner is going to limit the amount of tuners you can access.Currently in the process of putting in a new cam & lifters for my 5.7....I have a diablo tuner for the truck, who would yall recommend for custom tuning.
This is kit I'm installing in the truck below.
I do, running 91 canned tune at the moment, but getting a hemifever tune over the winter sometime. The 91 tune with the performance trans tune and mds disable is already a nice performance boost over stock,but the hemifever tune will take into account my cai and flow master flowfx cat back. I haven't had my diablosport tuner too long, but have had zero issues. I also kept my stock PCM just in case.Just buy your kit from Flyin' Ryan and get him to tune it with HP tuners.
No one uses diablows anymore !
