i have a 06 wrx with vf39 turbo and some others with tune! i put a new tranny in and everything is connected. now when you rev up the engine without boosting it revs fine but under any boost it misfires and breaks up to about 4k. i just changed the plugs gaped to .029 and no help. coils seem fine. the battery was left out for a lil over a month while doin the tranny can you loose a tune with that. really any ideas will help thanks
