havnt got one fitted to a ford, but have fitted them to my old mans last three japanese cars and theyved worked awsomly,

particularly on the evo, used an apexi acvr, and with enough setting up i managed to eliminate the boost spike, this ment insted of hitting 1.2bar (the fuel cut piont) and then droping of to 0.9 bar by 7k, i could make it hold 1.2 bar to the red line.

have alwaysed use apexi acvr boost controller.

will have the same affect on any car, deffinaly worth getting. and some of the new ones also display other information and act as turbo timers to
