Obviously they don't care, judging by their lack of response to this thread. lol

OK guys, here is the deal.
We at no point decided that we could not crack the code.
It was simply a matter of having the manpower and resources available to get it done.
We do have a new engineer here, that formerly worked at GM, and his first job assignment was to get our GM TCM support up and ...

I used the canned Predator tune when I added headers and catless mids. No codes at all.

I put the car on the dyno and only got about four more whp out of it working the A/F. The Predator tune works well with the headers/catless mids.

I figured it would. I'm thinking adjusting the injector slope ...

What gains are there with a predator tune on a 2006+ C6 corvette?

They also need to add support for the flash update that GM is putting in now. Some people have predators that they can't even use since the dealership upgraded their PCM software.

I was unaware of this. How long has the new PCM update been out?

Not sure, but be careful if you bring the car to ...

Really? I didn't realize that. So the canned predator tune on the U7191 deletes the rear O2 sensors? So if I installed headers and catless mids, I wouldn't throw the code for the rear O2 sensors? That's pretty cool.

Would you guys be able to send me a tune, tuned for the headers, and to delete the rear o2 sensors? PM me if you like. 2006 GTO

I am not at my work pc right now but we do not modify the IAT table too much from factory due to the fact that it is done very well taking the intake air temp and ramping the timing out due to the higher knock propensity of the hotter air, reducing it further will increase knock and thus knock ...

Hey Mike. Would you be able to get specifics on what timing is pulled, and at what temperature, with the U7191 predator tune?

I was just about to ask this question myself. An ETA on the TCM support would be much appreciated.

I loaded the diablo tune into my 2006 GTO, and I'm going to go out and do some data logging tonight. My question is....when I go in and modify parameters like PE, timing, etc., am I modifying the diablo tune that is in there right now to fix what needs to be adjusted, or am I using the factory tune ...
