I have the I2 and the tunes are nice but all the tunes don't seem to put out the power your saying. I'm not talking dyno runs here but 93 octane tune is a modest power increase and not the 90 hp and 90 ft/lbs. Don't get me wrong the truck runs great and shifts nice but I don't see the power increase 90hp and 90 ft/lbs should give you, that's a big difference in power, and I don't see it. I chirp the tires in first like I could in stock and barley chirp in second. the 87 octane is a nice smooth tune, and I like it but still underpowered as well, the 91 octane tune doesn't like my truck for some reason and runs very weird at WOT and takes way to long to shift from 3-4 AND 4-5 and in-between that time it shakes and seems stressed. I know you can adjust the WOT shift points and I have lowered them a bit to my liking. And yes I used the proper fuel on all these tune changes and drove 30-40 miles on each fuel before uploading the tune to make the trucks fuel system was full of what ever fuel. I've owned numerous ford diesels (6.0 and 7.3) and had tuners on all of them as well as a neon srt4 with a tuner and upgrades and a tuned evo. So I understand what kind of power 90hp and 90 ft/lbs should feel like. I have a 4" exhaust and cold air intake on the truck right now, and I'm a little unimpressed with the tunes thus far. My truck is running great in stock mode and there are no issues with my truck that I can see would cause this lower than expected power. I not trying to be a dick at all, I'm just being honest here. I may need to go to custom tunes to see what they can do for me.
