On a SRT-10 truck with disappointing results. The Guy only picked up about 70 rwhp (441 to 512) and that was with also adding long tube headers to the kit. And it only picked up 4 ft/lb of TQ. Seems like allot of money for those gains. Doing Striker heads, Cam, Headers, Tune on my gen 2 gave me 213rwhp. http://www.vtcoa.com/forums/f8/mopar-gen-iv-hybrid-install-underway-52031/ Anybody install this pkg yet on a Viper?
