Damn left cam spec sheet in toolbox, a little bigger than I expected pretty sure it is 228/588. It was recommended by Chris @ CBM motorsports , he's reprogramming my ecm wouldn't idle without stalling.
Its in my04 2500hd. It's a bit lumbier than I expected. But with the cats gone sounds pretty good.

So it's a 6.0 LQ4? Sounds like a nice combo, looking forward to the results

On my way engine light came on so I checked when got home and it was 2 codes for secondary O2s wich should have been deleted with the tune,good thing I'm bald cuzz I'm pullin my hair out with this tune situation.
