This is gonna sound dumb but i am new to mitsu. I work at a mitsu dealership it just opened a few months ago n we bought a 03 evo with S-afc2,manual boost controller,intake,upgraded intercooler,full exhaust,650cc injectors. the car ran fine when we first got it but the owner decided to mess with the s-afc n the car fell on its face. they had a guy come n try to tune the s-afc n he didnt have a clue wat he was doing. so i was the lucky guy stuck fixin it i got the car runnin better but it revs out at 4500rpm n it never used to do that n i cant really tune it if i cant go over 4500.i dont know if the guy who tuned it b4 me messed sumthing up but we cant get ahold of him.plz sum1 hlp me i am losing money workin on this car!
