plug color
hey guys i just changed out my ngk bpr6es for some ngk bpr7es, and the tips on the 6es where a nice white color. this means im running lean right. the plugs were in for about 6,000 miles. I have no idea what fuel pressure im running, the filter has abut the same amount of milege as the plugs. My next mod was going to be a 2gen exehaust manifold but now i guess im going to get a fuel pump and pressure gauge. I just wanted to put this out here to see if my thinking is corect.
thanks curtis
