I'm sorry for not originally posting correctly. I have a 07 Z06 (Brand New Stock) that I have recently programmed with my U7194 (which was recently programmed in my 06 C6). I have noticed absolutely no difference. As with my 06 C6 install, there was no options for 91, 93 or anything but the Diablo Tune. Am I missing some options. My U7194 is the original release with no updates (mainly because the updates dont appear to effect my usage).... Any info is appreciated.

Thanks in advance.

We have seen gains of 25+ rwhp in the LS7.
Check options>show last tune written to be sure it says Diablo tune, and not factory hp tune.

Here is a dyno sheet from a Z06 we tuned with the Predator tune on our dyno.

I would also ensure you are running good quality fuels. Mobil, Sunoco, Amoco/BP are all good ones.

Thanks Mike and Johan. I've checked under options and it does say diablo tune. I've always been a stickler for fuel and prefer Mobile 93 when I can get it. I used the same tuner in my 06 C6 and really noticed a difference but didnt notice in this car. It could be because the motor already puts out so much power and 25+ is a small percentage to the whole pic.

A final questions: If I install K&N filter (not cold air) and Mild2Wild will I need to make adjustments to the Diablo Tune. I've done a little reading of threads on this site and it looks questionable. Any thoughts are appreciated.

Thanks again,
Jeff

What is the mild2wild?
Either way there is plenty of adjustment in the tool to allow you to dial in most bolt-ons.

Thanks
