Haven't missed the Runoffs (mostly as a spectator) since 1970. My 04 mcs has build date 9/12. Would love to meet to discuss your mods so I can get better ideal as to in which order to spend some $$$. Was first thinking intake & exhaust first then, pulley & ecu after some miles to insure no major engine problems.However recently found out the 17" S-Lites NOT light... 25lbs. Now I'm considering Team Dynamics 17" Wheels @ 16 lbs. + es100 Yoks. as first buy. Guessing that would do the most to improve performance. Too many options. Hope to see some of you there.
