    Worked great but had to submit a request for a map to work with my vehicle which took a couple days. Feels more responsive, MPG unchanged. It's no miracle but I'd say it was worth the money. Fueling seems very clean (not too rich/not too lean, no flat spots in torque curve).

    The unit has performed flawless since installation in Spring of 2020. I used it's capabilities to change the gear ratio and to turn off the program that at cruising speed randomly shuts off cylinders. That feature was the best thing for drivability of my truck.

    This did not provide the immediate increase in power or mileage that I was expecting. It is programmable for max. rpm, shift points and firmness. So it gives you a few settings to play with. I had it way too firm to start with. After I eased off it ran much better. The acceleration is definitely smoother without that dead spot that was always there before. The mileage has not really changed yet, but I read that it takes a while for it to adapt to your vehicle and driving style. All in all definitely worth it. It is running smoother and faster now.

    5.0

    I have been using this unit on my stock 2005 6.0L for the past 4 years and have great performance gain while pulling my 15500 Trailer. Power gain has been over 20% and the fuel millage has increased greatly. I can tow with min boost pressure saving 40% on fuel. It mows the hills much better then stock. I could never pull the trailer with only stock programing. In addition the truck runs smoother and cooler then stock

    4.5

    I have a K&N intake and SLP exhaust also and with a 3.8l engine and a car that's not small, I can get about 35-38 mpg hwy and 30 mpg city all day long. The performance gain was noticeable, and I like that I can change the shift points and rev limiter (and top speed governor). I was hoping for a bigger change in the transmission shift firmness, I set it to max firmness and it is better than stock but I like a firmer shift that I suppose only a shift kit will provide.

    As for quality the buttons and wire adaptor are kinda iffy, but once its set up and programmed into the car it doesn't matter. It's not like a cell phone, it only gets used about 5 times at first to tune the car in perfect and then sits in a box. If your area has emissions testing my car was almost clean enough to breath off the tailpipe with the performance tuning installed.
