I ran a couple of months ago with i/h/e/ks and got 14.96 @92.3, last nigyht i went out and couldnt get fast than 15.1 @ 90. And now i have, ur pulley, es motor mounts, eibach prokits and new kumho tires. I dont understand, there was no humidity last night in MD, 2 mph slower in trap. i should be at like 14.6- 14.7???
