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

Only one way to find out. You might have better luck getting answers posting this over in the scan & tune section.
