I have a question on the use of the 2.5 timing key. Whereas the key will provide a linear increase in timing (vs. a programmed ecu), wouldn't one expect to lose some top end because of the advanced timing when it should be retarding?Originally posted by bikeman@Dec 12 2002, 08:38 PM
f7 with v force, 2.5 key, speedwerx hi flow airbox intake, speedwerx clutch kit, 24-39 gears. 111mph in 1100feet, 118 in almost a 1/2 mile. still has killer accelleration, great for trail or lake running. just run 91-92 octane fuel.
