I was disappointed with my 13 avalanche.. It had used 2 QTS of oil in 9000.miles.Was going to trade it for Toyota.I had read about this on net about AFM causing this b.s.GM made a mistake with this.The range kept me from getting rid of my Chevy.so far so good no more oil loss and it runs better than new.1 mile less per gal.and shifts smoother than ever and trans is running cooler than before and have smooth power all the time hope the range last a long time.Thank you Range technologies.

Worth the $$$$

Reviewed By Matt E (MIDDLETOWN, MO) Reviewed for a 2012 Dodge Ram —3/1/2015 9:07 AM

This was by far the best mod I have bought for my truck. Totally woke the 5.7 hemi up! Installation was a breeze and I got to turn the dreaded MDS off so no more drone. Took maybe 15minutes to save the stock tune and program the new tune. Totally recommend this to any dodge/ram owner.
