Hmm... No way my RS200 Auto can do 6.9. I think fastest it can go 0-100kph is about 8 sec. Engine is standard with no mod at all. Anyone can give me suggestion on what sort of mod I should do? Thinking of removing the catalytic and possible install a pod filter and exhaust. I'm trying to improve it's performance without making the car less economical.... Thanks in advance...
