I noticed the difference immediately

When I programmed my 2004 Vette for performance I took it out on the highway and immediately noticed the extra power. I just ordered a rear sway bar to handle the extra power. I love this tuner.
No noticable change with tunes

Heard others talk about considerable power increase with the Intune 1-1000 but I haven't noticed a significant increase in acceleration with either the Diablo tune or the 91 octane tune. Factory tune seems just as quick. This is a 2013 Corvette 427 Convertible.
