hi guys ...merry christmas

i have just put a 34mm restricter on my sti ra 95 took it for a spin and it is boosting at 1.5 bar and cutting out at about 5.000 revs . i am running 4 bar fuel pressure and an sx regulator . it was running normal boost before i put the restricter in but was still missing at about 5 ..i was told it was my old regulator that was the problem for the missing . i have changed the regulator now but get a dead cut at about 5 ish . the car will pull through it if i dont push to hard on the throttle ......anyone got any ideas ...quite urgent as car due out on its first rally in 3 days time ....thanks
