(make sure you use the hiigh octane with this setting or you get pinging inthe engine or just put the 87 octane setting and use that).

128 mph top end

6100 rpm rev limit

increase shift firmness

gear shifting
(1-2) raise it +3 mph
(2-3) raise it +4 mph
(3-4) raise it +5 mph
(make sure you don't use -3, -4, or -5. </div></BLOCKQUOTE>

Tim - What's the avg mpg with these settings? </div></BLOCKQUOTE>
Not sure hat the exact mpg is, but I do know there is a big difference in the way it shifts. I don't look at the mpg anymore. I just fill it up when it's close to empty. IT really depends on if 'm going up to Breck. or driving in town. It's not much of a difference to buy a power programmer for better mpg, but is for the shifting.
