Default Re: JET or PCM for less???? Need direction.

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

Just go to there website. Get in touch with Kelly. I pulled mine out and shipped it 2 day UPS on a Monday in California, got it back on Thursday. I didn't opt for the exchange or loaner. Super fast turn around. I'm very pleased with the results. I can't say there was a increase in mileage but there was in performance without a doubt.

Default Re: JET or PCM for less???? Need direction.

I had a Jet in a past truck. And same as Pewter, I wouldn't buy it again. I didn't notice any change in performance or mpg.

I've had the pcmforless in for about a month now in the H3. It was worth the money. I can notice a difference in performance (not huge but noticeable) and have noticed about a 1mpg increase over 3 or 4 tank fulls. I did the loaner program and it was painless. All told it was about a two week process. The security relearn happened just the way the instructions said and I didn't need to do it when I got mine back. My change oil message was on while I had the loaner but it went away when I put back in the original. Kelly was the person there I dealt with. She was quick to respond to my many emails. It was a good buying expereince.
