ECU Tune
I have a 2012 E550 Cab and am thinking of getting an ECU tune. I have narrowed it down to two, the RENNtech ECU+ and the Alpha Performance tune. The RENNtech ECU+ claims 540HP and 705 TQ at the crank and the Alpha ECU tune claims 575HP and 660TQ. I'm not sure where the Alpha tune is measured at. Has anyone had either of these tunes?

Had an OE tune this summer .... 500/600. A little more conservative but have had no problems at all with a good performance increase.
1/4 mile went from 12.44 to 12.05
