1. Performance, on 93 strictly. The tune works with 91 afaik, likely less power. Also downloaded the tow tune in case I need it. Specifically says don't tow with performance tune.
2. Negative, but I haven't lost a race yet lol. So far two chargers, a challenger, and some other random non notables on the highway in the graveyard. Been looking for a raptor to try but those guys never wanna race for whatever reason... Idk. Haven't bothered with any 6.2 trucks because the stock Ecoboost beats those anyways.
3. I didn't really hate the transmission before like some people do, but I can agree it was clunky at times. After the tune, it's butter. Zero complaints, pick up from any speed is on point. No delays, smooth shift up and down.
4. Great, love it. Power instantly when you want it, normal driving when you don't. Better mpg, and all around just a better drive. I have the mishimoto intercooler, turbo smart BOV, and roush intake- they all add in and benefit the tune, especially the intercooler imo.
Very easy to install, very fast response time to get your tune once you send your stock file in, support was available and straight forward/down to earth. The initial instructions are a little overwhelming and not super well organized imo, like it doesn't tell you first before anything to update the tuner on your computer - which i didn't and couldn't figure out why I couldn't save my stock tune until I called. After that the instructions are good.
I'm on a trip to NC right now from Miami, has performed great. Highway has been great, off-road great, have noticed zero downsides. I assume down the road some more maintenance on the turbos but afaik these motors are super undertones. The raptor motor is the same motor just tuner higher/higher output spec, this is basically a raptor in a box.
