Range Active Fuel Management Disable Device Reviews


So far so good

Reviewed By austin h (Corbin, KY) Reviewed for a 2008 Chevy Silverado —1/20/2015 8:33 PM

AFM dissabling device does what it says. I've used it for about 1,200 miles and gone from burning a quarter quart of oil to none in that time. My MPG has dropped from14.9 to 14.3 in the past few fil ups, but winter blend gas probably has a lot to do with that. I would recommend this to anyone that wants to stop their trucks from burning oil.

DiabloSport inTune I-1000 Tuner Reviews


Great Tuner with only 2 drawbacks

Reviewed By Chad A (Renton, WA) Reviewed for a 2006 Chrysler 300 —1/20/2015 3:41 PM

This is a great tuner with many options. My 2006 Chrysler 300 SRT-8 felt like it was idling just a bit off for my taste. This tuner fixed it and made it purr like a kitten. I did not really notice any high RPM power improvements however it does accelerate off the line a lot smoother now. This was almost a deal breaker. You have to pay $120 to get a vehicle specific tune vs bama = free AND are there are ZERO options to adjust shift firmness (You have to buy another $260 tuner to do that).
