Good information Patrick. Regarding the 1/4 times I've found that if you can duplicate the 60 ft times at the track they dyno is pretty damn close. I've had cars go within .1 and 1 mph at the track compared to what they did on my dyno.
We'll be seeing the effects of an ARH header and X-pipe setup soon on the G8
as well as a tune.

I am wondering if it is at all possible to do the G8 (LS2 block/L92 heads/L76 intake)engine swap (from our sponsors at SDPC --->) with a Camaro, and pull the same tune from it, +/- a few ponies here or there. To INCLUDE being able to use the 4 cylinder mode...?

I have not spoken with the owner in a month or two. At the time, he had reported some nice mpg gains on the highway (around 2mpg) because of the tunes ability to keep the car in 4 cylinder mode more often. I guess no news is good news.

Thank you sir! Hopefully if my wife doesn't change her mind we will be getting one for her and I will probably be talking to you about a tune.

For now, the TM is left off. The shifts aren't harsh like I thought they might be. We're going to go to the track and run the car with TM on and with it off. If no TM shows gains of less than a tenth, then we'll probably turn TM back on to extend the life of the tranny. We're just learning as we go.
Did you guys ever get a chance to run the car at the dragstrip?

As for on EFI which Pat G uses like he said, No.
