I purchased a 2009 Challenger 180 w/ 215 HP engine this offseason with 30hrs on it. After taking it out on the lake for the first time it would only rev to 2500rpm and about 10 mph. I replaced the plugs and was able to get the on-board speedo up to 29mph and revs to 6300rpm. It sounds like the supercharger is working as there's the typical high pitch whirr happening through the rev band. The shifter will go about 7/8 of the way to wot advancing the revs but the last 1/8 of travel has no effect on the speed or rpm.
Any thoughts on where to start? Maybe the RAVE valves? Bad fuel filter? Wear ring?? I'm lost.
Thanks in advance
