i have smoking coming out my exhaust from time to time but its only when i am idling and if i hit the gas it goes away. plus its whiteish smoke and it smells alot like gas soo i think i am running really rich since i have my check engine light on and the reason for that is the secondary o2 sensor. correct me if i am wrong but i think the computer is trying to fix the problem an its just dumping more fuel into the engine
i am really happy with my turbo kit. it made me fall in love with the si all over again and its a bolt on kit soo you and a few friends could soo install it yourself. plus later down the road when hondata releases the k-pro for our cars things will get soo much better for the turbo soo if it was me i would soo get the turbo but its completely up to you.
