Another 6.2 for 5.3 swap going on.

Well I don't know the real answer to the question above. I talked to a muffler shop who said he'd do the swap for $150. I considered what I thought it was going to take and decided that was a deal. Rather than drop the transmission support and knowing he needed to use part of the old one he cut the old one up to get it out.

When he tried the left side of the new pipe it didn't clear the transmission. As I type this I realize the pipe probably fit nicely with the 4L series but mine is a 6L90. In short he ended up chopping up the new pipe and welding it back together quite expertly. The fit is nice but I ended up paying $250 for all that work.

He should've honored the $150 charge. Not your fault he underestimated--maybe on purpose too--the job. When I give an estimate for a job and it's more work then I thought--I eat it. It's my fault. I can't in good conscience go over the estimate I gave the guy.

No, he went only on the information I gave him on the phone. It would be nice if he knew about the differences between the two models but even this group didn't toss that out as a possibility.

Took my Tahoe back for the tuner to finish. I thought I'd fill up with regular so I could run that. Unfortunately it seems the LS9 cam foiled me. Under light throttle it pings and he couldn't tune that out. He took out a bunch of advance so when I get my second tank of high test he'll adjust.

On the other hand when I punch the gas it's violent! I did not expect this big an improvement.

That's so good to hear that the swap is worth it. Its a shitload of work and risk.

On dry pavement at 30 mph I punched it and kicked on the traction control.

That's awesome. That's all I wanted from my truck. I was so disappointed when it still couldn't break traction even after cam/headers in the 5.3.
