SCT 3000 X3 Power Flash Tuner

I have a f-250 superduty diesel. This product made my truck come alive. The economy mode has been giving me over 17mpg going through stop lights and traffic on my way home from work. Mike was on top of things when I sent my information in on my truck and had my tunes emailed to me within 36hrs. I am only runnng my economy tune for now. The truck is more responsive and has instant trhrottle responce now. There is almost no lag now when you get into the throttle. Im going to try the street tune soon, but for now this economy tune is doing just fine. Thanks Mike!

Ordered this and got the custom tunes from MKM Customs. Service was great and tunes run awesome in my 2006 F250 Diesel. You won't want to go any more powerful than the street tune if you have regular stock head bolts on your engine. Only get the performance tune if you have studs instead of head bolts to prevent blowing your head gaskets.

I bought this tuner for my '06 Mustang GT to get rid of a check engine light due to a cold air intake installation. There was near zero documentation with the tuner and more importantly, if you want to tune another car (you trade-in your old car) THEY CHARGE YOU ANOTHER $150!!!! TO USE A $380 TUNER!!! Total crap. Buy with caution as they won't tell you this until AFTER it too late.
