DiabloSport inTune I-1000 Tuner Reviews

my review of diablo itune

Reviewed By Kenneth C (EAST BOSTON, MA) Reviewed for a 2009 Chevy Impala —6/3/2013 11:10 PM

I was most impressed by how fast it tunes your vehicle and goes back to stock in a matter of 4 minutes I mainly purchased it to eliminate my DOD it works I used the 91 octane tune and removed my speed limiter I tried both firm and hard shift mode which makes a big difference but I use normal shift because there are stories about my transmissions reliability my gas mileage is crappy with or without DOD it always says avg milage is 18.9

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.
