Spend all day yesterday istalling 243 heads ,cam, and long tubes. Now my new ECM should be in monday and off to get 3in mid pipes bent up. Should make for a nice increase, I hope.

 

cool, should be a nice improvement !!

 

what cam??

 

Any other engine mods done? What vehicle is the motor in?

 

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.

 

sweet! get some pics or vids up. who's tuning it?

 

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

 

Yep LQ4 , tune was late getting shipped so I won't have it till tomorrow. Guys from next shop over thought it was one of the muscle cars were workin on runnin. They couldn't believe a truck that new could sound like it does.

 

Finally got to drive my truck home last night. Pretty loud now think I'm gonna have to find differeent muffler. 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.

 

What all was done to the heads?
