Guys i put the intune on my 07 vette and love it,it does a real good job,i can tell a difference right off the bat when i pulled out.I put the firm shift tune with the 93 octane tune.Will be getting a custom tune from lew soon as i get my exhaust on.
My question is if any you guys used this and done both the hard shift and firm shift tune are they a big difference in the two or very little.I am happy so far with the firm shift,so far but was wondering about the hard shift tune because i have not put the hard shift in in yet to see if i like it.
thanks guys

I hear mixed reviews, some say they feel little difference, others report a more dramatic increase. Give it a shot, and see what you think

Hi,

Can you load Diablo 93 tune and not choose the FIRM or HARD shift tune, Or do you have to choose one of these? Can I do Diablo 93tune and leave trans at factory setting? If so, how?

Thanks

Not for sure,i have not tried it,i love the trans tune it was better then the engine tune.

yes you can. when the tool prompts you to install the tcm tune click the red x.
