How much more HP do these tunes add or how many secs faster does it take you to go from 40-60 mpgs at WOT? Most reviews say it helps but never quantify how much performance is actually gained by actual users.


Its not about the HP and TQ, its about the improved trans shift strategy and doing away with the lagging throttle response!

I bought the 5-Star for my rig, and the performance improvement has been pretty dramatic. The mileage has not changed, but the engine/tranny has given me what I paid for.

I finally got around to buying and installing this tuning program. I bought a new tow vehicle, 2019 Jeep Cherokee. Set it all up to tow, and towed it in the factory setting. Then I installed the program on my way home and it changed it completely on how well it pulled with the shift patterns after the install. I am quite pleased so far. Only have about a 100 miles on it so far. But going on a big trip in August and will give it a real good test. But really happy so far.

Ok. I forgot about this post. I got my tune 3 months ago. Much better drivability. I’m towing a 14 Explorer with 2 bikes minimum and now a kayak. The difference is incredible. No more speed limiter, I set it to the max speed limit of 125mph ( I could’ve removed it all together, but I didn’t want to be completely unsafe.
It accelerates much better, throttle response is much improved. As of right now I gained approx. .3 mpg. That was in cool weather. I’ll guess at .5 improvement max, which will put me at 6 mpg.
We are leaving on our east trip for 2 weeks on July 2nd, so I’ll have a good feel for how it is after that trip.

I found the 5 Star Tune was worth getting just for the improvement in the transmission shift patterns. I don't think there was any change in gas mileage. I do think it improves acceleration in such situations as merging onto a highway. And, I have the 5 speed transmission.
