the first run on the dyno the injectors had pinched o rings and flooded the engine. we quickly removed all the fuel and put a little oil down in. After we fixed the orings the car smoked bad for a long time but cleared up about 90%. The tuner said the smoke would be from the oil he put down in the cyls. But my mechanic said by the end of the summer if the smoking still existed he would re-ring it if it were his. but the car never ran good enough for my to drive so it just still there with this problem...
