I have a h/c/i full bolton car with 150 shot. i have 2 converters a ss4000 and a vig 3500 witch stall would be better with nos. I do a 1.62 60' with ss4000 on motor and 1.702 60' with 3500 on motor and 1.48 60' with 3500 on nos. but i like the 4000 better on motor only. so would the 4000 be to much with nos?
