DiabloSport inTune I-1000 Tuner Reviews


cool toy

Reviewed By thomas r (HUDSON, NH) Reviewed for a 2013 Chevy Silverado —3/29/2015 9:08 AM

pretty decent results from the canned tunes and adjustable parameters. kind of scary when it glitches. it has froze and also not recognized my truck a couple times but a pc update (calibration) has fixed it every time. I bought this to get a custom tune knowing that I could adjust the things that were most important to me with just the tuner. so far the canned tunes and adjustable parameters have made my truck more enjoyable to drive.

Superchips Cortex Programmer Reviews


Excellent programmer!

Reviewed By Darren W (DEFUNIAK SPRINGS, FL) Reviewed for a 2003 Dodge Dakota —3/25/2015 6:23 AM

I had an older programmer from Superchips. It wasn't updatable. This gives me an average of 3-5 miles per gallon on the 87 octane setting. Not to mention the extra power and torque. Not a lot you can change though. You can use it to adjust tire size to calibrate your speedometer. It also had a log feature that can be used to do 0-70 and up to a quarter mile run. Seems to be pretty accurate too! Loving my Superchips! Thanks AutoAnything!!
