The Pain Box Of hidden weird POWER...lol.. SO/SO
just having the two settings makes it very simple to work with one being the 85 octane and the other being the 91 octane gas. the ability to cool engine down faster is cool, distance and or speed calculation due to bigger tires rims ect the gas millage hasn't been here for me at all yet 1 mile more city/WHY that's it. pretty week on that as well as the other more intense locks that other programmers' can provide that this starter program sucks att. over all a sold C+
Did exactly as it said it would
With having larger after market tires on the truck and checking my speed with my GPS, I was moving 4 MPH slower than my speedometer was reading. After a couple of programming attempts to dial in my tire size so my speedometer would match my GPS. I am very happy with the results. Now my truck runs a lot better, transmission shifts better, and PMG improved.
Couldn't really tell any difference on 87 octane but it did seem to come alive a bit on 93. Throttle response is definitely quicker though. I'd probably buy again just because I've heard bad things about the more expensive units on the market. Don't really think it helps gas mileage either. I do however have a CAI on the way & put exhaust on last month so we'll see how all the mods work together.
