Recommended Posts

The results are in! Sort of. NicD hasn't tuned it yet. 425rwhp and 421ft-lbs. Pretty sweet for stock cam and no tuning.

Mods list:

Pfadt 1 3/4" headers w/ offroad x-pipe

Factory Z06 axleback

Callaway cold air intake

Cordes Performance Racing ported LS3 intake

Previous dyno was Callaway cold air intake and nothing else.

the big boards are going to have a field day w/ those numbers haha

LOL,

I agree Joe. Apparently, my gains were from the Vararam and not the headers lol. Gotta love some on the "big board" lol.

Wow, picked up 20/21 across the band. That's pretty dang solid. Once it's tuned nobody will believe the gains lol.

Here you go Dawg:

425/421 vs 405/399

It pulls noticeably harder and sounds sweet with the Z06 axleback opened up! The 13th needs to hurry up so Nic can tune it. :partydance:
