Almost. It was getting as low as 300. Throttle input didn't have any effect on it. I tried reloading the tunes twice, tried it with AC on and off, tried restarting. No luck... Load the baseline tune and it fires right up like stock. I dunno.
Lol an amazing feeling. I haven't drove mine in a couple weeks. Took her out for a little test drive after tightening axle bolts. It impresses me every time. 3rd and 4th pull stupid hard. Lund has an add on for the n gauge that shows boost.
