Let me start by saying OMG!! For the past ten years I've been running a plugin tuner which provided power but only at the upper RPM's. To get that power it turned my truck into a smoke factory and I still had to get through the turbo lag to get there. But with the Stealth Module I get the same power performance (on setting 3) with minimal smoke and the turbo lag is virtually gone. Pulling into traffic is no longer a nervous time waiting for the power to come up, it's there when you need it. Installation was a breeze, plug and play is the best way of calling it. To early to say anything about fuel mileage but for me the overall improvement is what I was looking for. Thanks Stealth Performance for a great product!

Very impressed with the way it performs. Love the option of putting it in low medium or high. I had it in high and lowered it to medium. The diesel mileage is better than before. I am gonna order a few more for my other vehicles.
