Steeda Charge Motion Plates
Has anyone tried the Steeda or JMS Charge Motion Plates? JMS claims they give you 10 additional HP at the wheels but Steeda said they only give you about ten HP in the middle RPM range and negligible at WOT. Both plates appear to be made the same. They get rid of the flapper in the intake ports and allow max air flow all the time. Also does anyone know if JMS used stock tires? It appears in the video that they are at least using stock upgrade wheels. I have all of these mods except the Charge Motion Plates and 4.30 gears but the kit offers your choice of 4.10 or 3.73 on JMS's site. The Steeda CAI with Xcalibrator gives 26.7 at the tires but JMS CAI and their Xcalibrator burn only gave 20. JMS also says on their site that they tried other manufacturers CAI's and they found that the sheild like Steeda uses does nothing for performance but if you look at the photos of their kit installed it includes a sheild. What gives? Any help would be appreciated. I'm looking for as much HP at the tires that I can get.
