DiabloSport inTune I-1000 Tuner Reviews


Excellent

Reviewed By Joseph I (Stanhope, NJ) Reviewed for a 2010 Chevy Silverado —1/27/2015 8:26 PM

I was looking into several different scanners to read and clear trouble codes in my 2010 Silverado. I read the reviews on the Diablo Intune and after shopping around, Autoanything had the best deal on it. I bought it, it worked as promised. I was able to read my trouble codes/check engine light, (have to decipher it online), and clear them. I was able to shut off the active fuel management on the 5.3L motor and did the 87 Octane tune. MPG improved as did performance. Highly recommended!

Works Great

Reviewed By Daniel H (Denver, NC) Reviewed for a 2011 Chevy Silverado —1/27/2015 3:14 AM

Does exactly what they say it will. No more annoying 4 cylinder mode! Only thing I wish it had was an on off switch. Can't believe that if they were smart enough to design this device that they couldn't include an on/off switch. The plugging/unplugging issue is a PITA if you don't drive your vehicle every day. Hopefully they will come out with a fix.
