oh ok thanks , cuz i wanna race my buddy 04 stock sti froma dig , but i think i should wait to get a dyno tune first cuz i already beat him from a roll , but one day the car runs good and one day it runs very rich , last time i raced him from a roll tha car was running very rich and every time i slow down the car just die and thats when he beat me when the car is running rich
