Whats up, ive had a sr in my 510 for about 4 years now its all stock, but lately its been smoking like crazy when its under load, i know its running really rich but i doubt its that. Its white smoke. Does anyone know a good engine guy cuz if its the rings i wanna upgrade, or if its the turbo i wanna do the same, and also the guys that did my swap kinda half assed it so it needs some clean up. Any help would be appreciated.
