please help
i tried to fit a boost controller today a evc 2, i double checked that i had installed it correctly disconnected the vsv and off i went(with the ebc switched off to check that i could still get stock boost) all was fine untill the car heated up and i gave her alittle boost, it then started misfiring, so i after limping home

(luckly wasn`t to far) i triple checked my install but couldn`t find anythin wrong, so after giving up, i disconnected the whole thing and put it back to stock, but still the car wants to cut out and i would take a guess that it will still misfire under load as well, i read the error codes and came up with 42 how could the speed sensor course this, where could i have gone wrong??
please could i have some advise
