Question about tune? I recently installed a lid, 3.73's and got a tune from wait4meperformance on my 99 ws6. The previous mods on the car are 3800 yank stall, fl headers and a off-road x-pipe. With the previous mods i went 8.08@85mph with a 1.77 60 ft. last year. I did take it this year before the new mods and could only hit a 8.20@84mph with a 1.82 60 ft. but i had a bad o2 sensor which is now fixed. With the new mods added the best i can get is 8.13@84mph with a 1.76 60 ft. Any ideas why i only went from 8.20 to a 8.13 with a lid,3.73's and a tune? Could the tune be off?
