DiabloSport inTune I-1000 Tuner Reviews


Must Have.

Reviewed By Edison U (RIVER RIDGE, LA) Reviewed for a 2006 Chevy Impala —1/4/2013 7:04 AM

The DiabloSport inTune in my opinion is a must have device. After the tune, engine performance and torque is immediately felt. Also, got 2 extra gas mileage per gallon improvement too. For this reason alone, the device will pay for itself in just a year.

Great product

Reviewed By Bill V (BERLIN, NJ) Reviewed for a 2000 Ford Ranger —1/3/2013 8:53 PM

I've had it for about a month now. I've been using the gas saving mode. Works very well, but adjusting from the laggy stock shift from my 2000 ranger to a firmer, faster shift was great. You start off wanting to play with the shift by gassing a little too much, but once you get used to it and start driving like a reasonable human being, you start saving about 2mpg or even more depending on your driving habits and road conditions. I've used all the modes except for tow.

Chicago Chuck : 2002 Chevy Silverado 5.3L 4x4

Reviewed By Charles S (GENEVA, IL) Reviewed for a 2002 Chevy Silverado —1/3/2013 5:29 PM

Couldn't wait to get this thing. Registered it online (3 min). Then plugged it in and programmed it to 87 Performance (2 min). Wow, it really makes a difference. I had my son drive it to confirm what I thought, he agree'd, noticeable difference in performance. Then we tuned it to Fuel Economy (another 3 min), performance is better than stock. Too early to tell on gas mileage but I hope it improves, that's really why I bought it. Will keep you posted. Fun Gadget, It Works, I Recommend It.
