I was just wondering how long did it take for you to become bored with the output of your car after a major upgrade in performance? As of late I have become bored enough with my cars performance to seriously consider a Zex kit. I always thought if I just had 300 I would be satisfied...well 600 miles on the mill and I'm officially accustomed to the 'feel' of the car in second an third and want that PUNCH that I felt the first time the new engine saw the redline...I'm willing to bet a nice 75 shot will help that out. Anyways...who else and how long did it take for you to become...bored?
