Easy To Use Performance Programmer

Reviewed By Larry F (Millington, TN) Reviewed for a 2003 Chevy S10 Pickup —9/18/2017 1:31 PM

This programmer could not be any easier to use. I recommend going online and print a copy of the instruction manual (about 5 or 5 pages) because there were no instructions with the programmer. Most people won't need the manual, but nice to have. I went for the highest setting that requires high test gas, firm shift, and 10 mph higher shift points. I did notice a little more power, but the real winner was the transmission, with much better performance. Good buy!

Range Active Fuel Management Disable Device Reviews


Power!

Reviewed By Austin L (OPELIKA, AL) Reviewed for a 2015 Chevy Suburban —9/15/2017 12:54 AM

Since I bought my wife her Suburban, the AFM system was driving us crazy! It would kick in and out and cause a terrible exhaust drone that bothered everyone. Since purchasing the Range AFM Disable Device, we actually enjoy taking the Suburban out and getting constant and consistent V8 power. Gas mileage has stayed about the same @ 18.5 mpg but without the lag of the AFM kicking in and getting "tripped up" on itself and not shifting correctly. I highly recommend this product!

DiabloSport inTune i2 Tuner Reviews


It's okay, but I've used better.

Reviewed By Jacob S (MILTON, PA) Reviewed for a 2002 Ford Mustang —9/14/2017 9:43 PM

It's not a bad little tuner, but for the money I wish it would be a little faster. My SCT tuner loads tunes in only a minute. This one however take 3-4 minutes. Really racks up the time on the dyno, which cost more money.
