The tuner would not read my VIN. It only had one setting (street) and not the four that it was advertised to have. I can't even use it at all. What a colossal waste of money. They won't accept any returns on open electronics. How am I supposed to know if it works if I can't open it.

Love this tuner! Don’t believe all the negatives you read about these, call and talk to Clay if you’re nervous about purchasing one over a hydra, he’ll help you out! Can’t say enough again about all the Riff Raff Diesel folks…you folks are awesome and have a customer for life here.

This tuner does everything you need it to do. It comes with preloaded tunes which work great but if you need custom tunes it's capable of that as well. Sct is the way to go when you need tuning for your 6.0

I give it a 5 star cause I’m impressed but never had or used one but this thing worries me I have it on street tune and that’s enough for me. Day and night .trust me u will b satisfied

I have a hyper chip in my other truck . I like it much better.

Got the programmer before I expected. I did the update like instructions stated. Tried to program my truck and found that I got a general error code. Contacted SCT and found that older models can’t be updated. Resolved that and did the reprogram. The street tune is great for just riding around. The proformance tune is crazy on my 7.3. I did notice that it will make my clutch slip in 4th and 5th gear. Programmer it’s self is great.

work's really well.Just wish it said what the hp gain was going to be.

Super easy to use. Also sct has a amazing customer service when u have a problem.

Unbelievable product that really lets your truck show it self, 20 mpg urban driving on street tune while hauling butt 2000 7.3 6speed, cab and half short bed. Recommend to all POWERSTROKE owners.
