Just had to give feedback..I have an 05 hemi 4x4 that i bought mainly for work last month. I get re imbursed .55 a mile and drive 40k a year ez. Im not new to these trucks but i was really curious to see if a tuner would increase my mpgs. I live in so cal....I was averaging below 10 on streets...a high of 16.5 highway and 11-12 average mpg which is right on spec for fueleconomy.gov. I uploaded the economy tune and instantly I was seeing 21 mpg hwy...wtf wow!! this is a non mds truck. I confirmed these results throughout the day.....mpg on highway increased 3-5 mpg. I drove out a tank of gas today.....and ended the day just over 14 average....which is a very solid 2-3 mpg gain. However this was with a TON of LA traffic which normally would have destroyed my averages.
anyhow Ill play with the performance part of it next time I get to the eighth mile...I did purchase the optional 40$ advanced trans tuning option and look forward to fixing the lousy downshifts these trucks have.
Worthy of noting I did experience slight ping while playing with the 87 tune...but my plugs could be old and truck is new to me. it also outright stalled on me at a signal today...but only once...ill be keeping an eye out for that.
So far im blown away by the results...ill update as the miles pile on
