upgrade..shift limiter

Reviewed By Jeff T (Milwaukee, WI) Reviewed for a 2003 Chevy Monte Carlo —5/27/2012 11:41 PM

required upgrade before use. installed disc, then during final installation, malware notice popped up and wouldnt install. had to remove spyware blocker before would work. malware notice still on laptop.... :( took many tries to get the right combination for the car to run and shift smoothly. still hits rev limiter from 1st to 2nd gear sometimes. notice difference right away though, especially shift firmness, has to be the best upgrade from the whole thing! during install on car, shows interruption sometimes, then restarts upgrade. very odd

Worth it for towing

Reviewed By Michael Z (Wolcott, CT) Reviewed for a 2011 Chevy Silverado —4/9/2015 6:04 AM

I saw the reviews for the I-1000 and decided to give it a try. I saw a small difference in the 87 tune so I decided to try the 93 (Diablo tune). That made a big difference. I'm now able to climb hills in 5th where the truck used to downshift to 4th to climb the same hills. And by climbing I mean actually accelerating in 5th while climbing those hills. have also seen a 2 mpg increase. I'm going to have a personal tune done as soon as I can come up with the cash. Well worth the investment..
