received tuner on Monday. I filled the tank up with premium (91 octane) and went home to install my tuner. install on pc took 10-15 minutes, it auto-ran a couple of updates. 30 minutes later I grab the keys to the truck. 10 minutes later I get it plugged in (had to loosen the OBD2 connector, no worries). installed and chose 91 octane. I noticed that my differential wasn't listed (3.73, factory gears) so I send a quick message to the folks at Diablo, we should be able to get this squared away with a minor update. I change the shift points and stiffen up the shifts (don't increase your timing, according to Vas @ Diablo, I trust him on that) and go for a drive. rats, I thought I would get more than this. in fact, was this just a "placebo effect"? so I go back and forth and uninstall and reinstall & I can feel a minor difference but .....um .... seat of the pants I think I just spent $200 per horsepower. I already requested a return from RealTruck and we'll see how it goes, maybe I'll just friggin keep it and see if I get some extra gas mileage.
at least I have my honda hornet!
