2.5 missfire poor running
hi there any ideas would help , just spent all my hard earned cash on 2.5 conversion on my sti1. gone normal route with a sbr gt12 gt30 cart , fuel pump , reg ,rails,740s,uprated oil pump etc etc etc , well prob is poor running oh also link 6 row to be mapped by pat , run car in was running a little rough running in ,smelt like over fueling , fouled plugs up once and had to clean , done compression test 165 all cylinders fine ,checked fuel rails no leaking , when throttle is held at a rpm eg 3000 revs stay but car splutters every so often and pops out of exhaust , when you rev engine seems really slow to pick up in low revs then picks up at around 2500 rpm and seams sweet as a nut , any ideas guys thanks much appreciate any help gazza
