hey guys whats up
ok im running 9lb boost on my spec and for some reason when ever im in full throttle, at 4 - 5k rpm theres a split second misfire, sometimes 3rd gear sometimes 4 sometimes th i dunno what it is, i have wrx plugs, wrx injectors, stock pump...the best thing i can think of is to retune??? last time i tuned was a few months ago, and ater the tune i changed my plugs thats all, should i retune ?

Whats the part number of the plugs you have? You might have the wrong heat range. Also, check the gap, iirc the gap has to be like half the amount of an NA car. Not sure though, cause 9psi isn't all that much to be blowing the spark out. Do you have a wideband? Maybe in that range the SACF isn't giving enough fuel...? Trouble shoot man, get it on a dyno and log what your car is doing if you feel it's a real problem, ...and if you do stay out of boost till you figure it out!
