Ok just got my car mail in flashed to my mods which are 3inch tbe (highflow cat),injen intake with upper hardpipe,225 walbro, greddy rs. Thats pretty much it, the car seems to run a bit better but for some reason it smells alittle rich through the exhaust. Reading through the previous post on this people say look at your plug,ox sensor, and possably do a log. Any advise would be appreciated.
