I have an electric fan, jet pulleys, jet thermostat, jet stage II, 52mm TB,
billet spacer, My Filter kit, JBA Y pipe, Headers, and a Flowmaster 2
MSD 8.5s and the Accel coil........
Stock Gap is 40, I had opened it up to 55 but mileage took a dump. What gap

confusing. Any ideas?
The only 'performance mods I have done are MSD 8.5MM Super Conductors, Accel
Super Coil, Champion Truck Plugs, MSD 6-Offroad Ignition Box, and Borg Warner
Select Brass Cap and Rotor, and a 2stage Amsoil Air Filter. After putting the
MSD box on, I opened the spark plug gap up from .035 to .050, and noticed no
increase or decrease in city gas mileage, but did notice an increase in
highway mileage. I get about 50-75 miles more per tank now. I am going to try
a smaller gap this weeked when I take the plugs out to see if they need to be
