I just spoke with Unichip and they verified what I stated in my post above. We can't just look at the 15:1 AFR and freak out. They saw AFR's as high as 15:5 in testing. Stoich is 14:7 in closed loop, but the Tundra will go well over stoich to increase mileage in certain situations, even under partial load like in a towing situation. You can't go full throttle on a dyno without downshifting. This is the problem. Unichip did well over 100 dyno runs for the 5.7 and none were the same. Some showed 40 hp increase, others 40 hp decrease, and everything in between. But, on the track and street, the tuning is perfect and a 0-60 increase of .3-.4 seconds as stated by Unichip and verified on the Gtech, is achievable. The problem on a dyno is that its impossible to hold a gear on the Tundra. Our sport shift sucks. It should allow us to hold a gear without not only upshifting, but downshifting as well. It will constantly downshift under full throttle and trying to hold one gear by feathering the throttle will produce inconsistant results due to varying load. Wheel speed sensors sense when the rear wheels are spinning faster than the front and will pull timing. Its more complicated than I can fully understand as well, but they are confident as a company that it is not the Unichip, and I trust them. Do you think that in all their testing, they didn't encounter the same problems? Unichip stated that they trust Gtech measurements more than dyno measurements for the Tundra. I forget which member used his gtech, but he saw definite increases. They stated that with all new cars, they are seeing the same issues, and they are trying to get this new V-Box performance measuring system which will replace their dyno for getting accurate real time readings of AFR's and hp/tq.
Unichip has attempted to contact That1Seven and I believe 2mtt also. Their phone calls and emails have not been answered. They asked me to apologize to you again for what happened yesterday. If you don't have time to respond, so be it, but don't say that they have poor customer service. they are attempting to contact you to remedy the situation. If you would like, I can PM you personal contact numbers. Just ask. I have all of their personal contact info. Unichip will be posting later today. I asked them to explain things in laymens terms. In our discussion I was reminded of a fact that I mentioned earlier regarding the high octane map. If you don't have access to high quality 93 octane, DO NOT run the high performance map. You will get pinging and poorer performance than stock if you run crap gas or 91 octane.

On another note, Unichip has not stopped testing on the Tundra 5.7 & 4.7. They aren't stopping at simply adjusting AFR's and timing. They are investigating and making impressive progress on adjusting several other features from what I was told. They asked me not to divulge any additional details yet, but I'll just say that there's certain people on this forum who will get their wish and those that freak out and sell their chips will be very upset. They will be releasing updated maps and components in the near future. Glad I got Flux!
