My dealer put a waterpump on my LMM that was leaking and it had built trans 500+ tuning and everything else and they never said a word. Luck of the draw I guess

No tuner? Just delete the sh#t, lift
pump and let her eat? Whats that last for, about 50 miles?


well duh on the tuner lol



I just hate to lose my warranty. I didnt need it with my LBZ but I may not be as lucky with the LML. I am pretty curious to hear it with a DTS down pipe and 4" straight pipe! We'll see?

I just don't see how they could relate a tuner to a leaking rear main seal. Or something like a mirror or a window motor

It will void the powertrain warranty, not the bumper to bumper. The tuner could allow higher RPM and/or create higher crank case pressures that could cause a rear main seal to leak (that may be something GM could say about why they wouldn't cover a rear main seal leaking).

Is anyone running the quadzilla yet

I got the update for it today so that it will load onto my truck. However, I have been sick as a dog and have not downloaded the update.

I guess I could get my ass off the couch and get it rollin. I will start a new thread about my findings.

custom tune

assuming i was able to download the stock tune to my laptop... would efi live recognize the format? I know its illegal to alter the stock tune if its downloaded from GM but im just curious if it could even be loaded up into efi live or a similar program.

I have not seen the format used on the LML tuning but from what I have heard it is not likely.

Lmm swap

Since it seems tuning for the lml is far away. i wanted to know if you swapped lmm ecm fuel system and heads onto an lml, would everything still work properly? I assume the exhaust brake would be inoperative but would everything else work like factory?
