I'm was basing the gas market to be the same. I'm the one of the few that feel that it's not for the better. I used to build transmissions professionally so I know what it should not be doing and I don't feel like doing a rebuild just yet.

Example of one type of shifting, getting on the highway the truck will lug in 6th gear, give it pedal, stay in 6th, give it more pedal, still 6th, then a little more pedal, it would drop a gear, then drop another gear and be at redline, then shift again. It would literally rev to the moon for 1/2 a second and shift back into 4th. Not smooth at all. This is with 4:30 gears.

I called Mike to talk about the issues with performance tune and he told me he knows its better and if I do not like it load the performance and tow. My first impression of 5 star and the customer service is not good. I just wish when they advertise that it is great for everyday driving it would be and not tell me to have my father load a tow package when he never tows.

Overall if I did it again I would search even more and probably not go with 5 star.

Solid shifts, great power, and good customer service. Pretty hard to beat. The gripes I have heard are few and far between


YMMV

I'm not a fan of the 5 star tunes' shifting either. When I first got the tunes, the idle speed was set too high, close to 900 and it would want to roll through the brakes if I didn't keep a lot of pressure on the pedal. He adjusted the idle back to stock for me which worked... adjusting the idle speed in the options on the tuner did nothing. Throttle response = great. Shifting I don't like.

On the 87 perf it sometimes slams into 3rd and always hunts between 4th and 5th seeing as I drive in traffic that varies between 40 and 45 which is annoying. Plus the converter doesn't lock until 50 with this tune. Mileage is definitely lower than stock (not a big deal to me).

The 87 eco tune shifts too early just like the stock 2011 I had. It wants to be in 6th with the converter locked at 40 and lugs the engine. The stock 2013 shifting is much better than that... it won't go into 6th until 45 unless I'm accelerating. Didn't leave this in long enough to judge any changes to mileage.

The 93 perf tune has shift points raised like the 87 perf tune only it shifts harder and will chirp the tires if you get into it. It's fun but impractical for everyday driving.

Haven't tried the tow tune.

Stock, the truck shifts fine- no flares, no slamming into 3rd just like another poster mentioned. I'm running the sct 87 strategy tune that comes with the tuner and I like it better than the 5 star tunes... mileage is the same as stock, it shifts normally without doing anything weird or unexpected, has a little more power and will hold 6th without downshifting better than stock. I am probably going to sell the tuner pretty cheap here shortly, it just wasn't what I expected.

I had revised tunes sent that were better. My major concern was with every tune I would get a 2-3 shift flare and occasionally 3-4 when I would do a hot start. Never did it stock and goes away when it's returned to stock. The converter unlocks too quickly and stays unlocked a long time. Lots of hills in the area so the converter in and out all the time gets old. Looking for suggestions on a different tuning to try before I toss the tuner all together, it's been returned to stock for a while now and drives fine.

Our performance tune has the firmest shift points while the tow tune is milder shifting while maintaining engine performance. For comparison sake have you tried any of our other tunes? This way I know where to begin to revamp your performance tune. My apologies your first attempt to fix it did not go as they should.

Also unlike many, I prefer the stock tunes ability to shift into 6th below 50mph and when stock it shifts in and out of 6th very smooth. However when it has the 87 tow tune in it it slams real hard back into 5th. I think I will keep the truck stock most of the time as I like it much better hauling my flat deck with 8000lb of water on it.
