So far... there has been a VERY noticeable difference in acceleration. This is not surprising given the stock's inertia. Whether the programming is worth $289 for those in the know I can't say. Me? I would not want to spend time to get the doohickey that will allow me to "do it myself". To me getting my desktop or laptop worked on would be about the same price. Basically, if this increased in performance proves itself on the road to MOAB this Summer, it would have been worth it for moi. Otherwise, I might just be self-fulfilling my wish now .

Can't say about MPG at this time.

Well I lived in Charlotte up until 4 weeks ago so I bought a tune from them and was able to drive over to there place have them flash the PCM. I then pulled an enclosed trailer weighing in at 3000 lbs running 70-80 mph on interstate got 13.8 to 15.1. 1 round trip of back and forth to work normal milage was 18.7 it bumped up to 19.6. Moved to the Orlando area ard I'm in 20 miles of stop and going and getting 16 mpg. Pickup is noticably quicker shift point changed to handle the trailer better and a stiffer shift as well. So far i'm very happy with it.

So has anyone ever had the PCMforLess or JET tune dynoed? I think I missed the answer, if it was posted, due to the flying fingers and fruit

i have the pcmforless tune and it is gr8
the 3 runs alot better now
the difference is night and day
i own a towing and repair (mechanical) business (over 20 years now)
so i do have the background to make that statement
even the dealer said it was awesome after driving it
best running 3 he has every driven

Great feedback! Thanks for the heads up. For those who used PCMFORLESS, what was the manner in which you contacted them? I think I am ready to bite.

Thx! -C
