Now I was not aware you had to use Premium fuel when you use this item so that was my first let down. I installed it in roughly 30 minutes. Easy install. Very noticeable gain. I would guess almost 20HP. Better shifting too. So the shock of having to pay more for gas died down because I was happy with the gain.

BUT

I went from roughly 15-18mpg (all city driving) to around 10-12mpg. I am not over exaggerating. I took it off for a few days and mileage went back up. Put it back on and it shot back down. I knew I would lose some mileage but never expected that much. That combined with the more expensive fuel runs the price of this thing up!!!!

So even though I love the gain I am selling it on ebay for $200 (paid $289).

This is just a warning to other people out there who might consider getting one.

I did call Jet Tech support on this and they asked a few questions about when I had done my last tune up and how the truck ran before I put the module on. In the end all they could say is that there is going to be "some" loss of economy when using this product.
I did a tune up not too long ago (full tune up) and my trucks engine only has 24,000 miles on it (swapped out a few months ago from a wrecked Blazer). So my truck is in good mechanical condition. If you plan on getting a module and your truck is in worse condition expect more of a decline in mileage with it.

Just my two cents on this product. If I was not on a bidget I would keep it because the gain was very nice. Just could not afford expensive gas and using so much of it.
