Each to there own i guess if you want your engine to run to its full potential the Power FC's don't cut it anymore, all the cars I'm building from now on will be run on Vipec. Richard Supra has V88, Kingy's R34 is getting a V44 put in after we get back from Vegas, R32 has a V88 and i'm putting a V44 in the 180SX the old Power FC will be getting Frisbee out the window. I have never had any problems with the Vipec so easy to use, setting them up is piece of piss, wiring them up easy, setting up launch control, flat shifters with ignition cut, anti lag you name its got it.
