ok i bought my 93 fd3s with this computer set up.i just put a new rebuild in it because i bought the car with a busted engine.every1 is telling me to change it-tune-it-what ever.i dont know how to tune it at all.i dont know it like that.i only got the car with these mods.all are pfs. intercooler,3" turbo's back-no cat(i guess the apex seals took them out)lol,air intake set up and the purple comp set up.i was going to unplug it but i was told the factory ecu will not suport it.and sugestions/help will help me out so much.thanks, jason

the pfs boxes have a reputation for being finnicky and glitchy, although it can be setup to be reliable.



your best bet for reliability would be to put the stock main cat in, and keep the boost under 10psi

its cool. i just replaced it with a apexi power fc and commander.and its getting tunned this sunday comming up.later, jason

car already runs better huh?
