Does anyone have some data for how the L92 engines take to the Diablo tune? Also for a relatively stock truck (intake & cat-back exhaust), is dialing the LTFT's enough and thus a custom tne really wouldn't help much more than that?

And Mike, do you think that when/if TCM support is available is it likely to be an update that we can download the the U7194?

Yes, it will be an update that you can download.

As for the 6.2, all I can tell you is it adds a solid 25 rwhp on 93 octane and wakes that thing up a lot.

Perfect, thanks for the info mike.

I'm going to have to order my predator soon.... Just can't justify going with anything else especially with my previous experience (btw my 1/4 mile time on my 05 5.3L went from 17.4 to 16.6 with just the 87 octane perf tune! 33 inch tires/ back to back runs)

Mike,
When I get my programmer do you recommend a custom diablo tune or will dialing in the LTFT's be plenty?

Thanks again
