Just talked with Jamie....I do have the stock thickness washer on the injectors. The thin ones are going in as soon as I get them and that will curb some of the idle have and low speed smoke like it did on my 370's. I still think they are a big but Jamies says with some fine tuning and the thin washers I can make them work. I'll give it a shot. My HX cleaned them up easier down low because it spooled faster.....this Super B is bigger so it's gonna spool slower.....so I'll give it some time and tuning. I'm to the point where it's borderline DD and fun vehicle so I'm going to have some "drivability" issues especially since it's a 12V and timing and such is static.
