I have found these guys to be more realistic. I have used them before on other cars with no issues. Power graphs are shown. Hopefully I can pick one up in a few weeks.

decided to try the 5950/5950 for giggles, the lag was horrible. for my truck, 6100/6200 is awesome and day/night compared to the 5950 wot tune.

still waiting on an update for the TM/3 day dl for free posting...

 

i tried the 6100/6200 and it was horrible on my truck. shifting into third it would "stall" for 2 seconds yet stay at high rpm. So now im at 6100/5950 and that works for me

 

I have had mine for a while now and tried some different tunes (all quick tune) I can't say the 87 does much, but it shifts nice and smooth like stock (higher RPM though) but when I go to the 91 tune, during part throttle driving around town I get a surging shift, I can't tell if it is when the MDS kicks out or not, but it is starting to bother me. The 93 does it too, bu t not as bad, my 91 tune sucks I think. Wide open are nice an firm and I wouldn't say there is anything wrong with the way it shifts at WOT. I have updated my tuner a few times and it says it updated the truck database for gas engine, but it still seems the same. Anyone else notice anything like this?

 

I'm returning mine.

I tried several settings, and none of them were right. I'm not gonna keep messing around with bad tunes and screw up my trans or the valve train. After waiting a week for my original bad tune, it's now been another 6 days since they said they'd look into this issue and I've heard nothing.

I also tried turning off MDS twice, and it stayed on both times.

 

So I have 2 towing related questions that I can't seem to find answers to. Wondering if anyone could help me out?

1. When in the Mileage tune or 87 tune, I know you're not supposed to tow, but what exactly happens when you push the tow/haul button? I had a load of 20 bags of mulch and pushed the tow button and it felt like it was the stock tow tune.... Is this the case?

2. When in the tow tune, do I need to push the tow/haul button? Either way, what does pushing the button do? Revert to stock or is it also specially tuned in the tow tune?

 

any new updates on the release of TM? Just don't want to miss the 3 day freebie...

 

wow, you guys are shifting high, this week I went from performance 93 quick tune ( 5600 stock shift points ) to 5850 shift points and thought it was a definite improvement from the stock shift point, I am hearing chirps with the 1-2 shift, need to make sure it is not the serpentine belt or will swap out for a gatorback belt. Need to flash to stock next week for the 25k dealer visit but I will bump up to 5950 after that. No hesitations between shifts at all, this thing is on the money.. also looking for the update to completely disable TM, will roast the tires at a red light with ESP disabled now, can't imagine what 0% TM would be like.

 

Nice feedback.

One thing about TM in the new options, I wouldn't set it at 0%. Reason being, the shift completes faster with some TM left in the mix, say about 8%. We found this during testing. 0% actually will slow the shift down. Want a quicker shift, leave some TM in there. With reduced TM, the shifts are even more amazing. My 08 shifts like lightning.

The options should be releasing very soon.

So I take it that nobody knows the answer(s) to these questions?
