TJ brought me the car with an FRPP intake and FRPP pro-cal tuner already installed, we baselined the car with those two mods at 483RWHP, pretty healthy, considering the FRPP parts claim a conservative 40hp gain. Most stock GT500s will come in around 420-440rwhp, so it is right where it should be. The FRPP tune is very conservative because it has to work with poor quality 91 oct fuel and is used on a production car (the KR).
I then added a custom VMP tune for our local 93 octane fuel and picked 33RWHP!, taking it to 516RWHP.
With the addition of a VMP 2.65" pulley (adds 3-4psi) the car made 544RWHP, a gain of 28RWHP.
Not bad for just a few mods, TJ left with another 60RWHP and nearly 80 more ft/lbs in the mid range.
