I HAVE A STOCK SUSPENSION CAR IM BUILDING AND DIDNT KNOW WHICH SETUP WOULD BE BEST FOR NOS TO GET DOWN THE TRACK????
Whoever told you that... is on the pipe real hard...I have both but only use the progressive to tune. MSD told me DO NOT USE TRACTION CONTROL with nitrous. I would like some input from those who have used traction control with NOS.
Here we go with the traction control thing again...I think what Jon is referring to is the slew feature on the 7531 with nitrous. Slew drops out cylinders when the RPM climbs faster than the preset curve. Dropping cylinders (not firing them) could cause problems by unburned fuel getting lit the next stroke and lifting a ring land. The Davis is fine with nitrous, it just retards timing until the sensor is satisfied with the wheel speed.
