whats your best guess?
my car is running like crap right now and im pretty sure it just needs a tune but i wanted to see what you guys thought. so i have a 2003 wrx with a ej25, perrin fuel rails, sti injectors, vf34, mrt intercooler, catless dp and catback w/ the stock ecu. so basically when i try to rev the motor it stutters all kinds before it actually revs up (like trying to rev up a cold dirtbike). and just flutters no matter how cold or hot the engine is. and when i shift it shakes and again stutters. its not super consistent though. it just does it half the time. im currently running a cobb map stg2 for the vf34 and sti injectors and catback and still does the same thing. a friend told me the timing is probably a little off its running to rich. what do you guys think?
