about a year ago the only upgrades i had done to my cougar were a coldair intake and no cat converters and pi upper manifold..it ran a 14.88 then...last night after my pi cams and blablabla bullshit even a ****ing tuner..i ran a best pathetic time of 15.31..what the ****!!!!! how did i lose that much time expecially after doing all these mods? i have no engine or trans or hooking up issues..i even stripped the whole rear end of the car out..what a waste of time...any idead why i lost so much time? and also it was 69 degress with next to no humidity, so it was perfect track conditions..see my signature for list of upgrades and tell me whats wrong..do i sell myh superchips tuner and get an xcal and see if thats makes it better? my buddy has just a 70mm plenum 78mm mafs and a xcal..i beat him by like .010 only and he also has a cougar..i dont get this..can it be the tuner i have isnt good enough?
