With all that you ran a 14????????????
No freegin way....you have a problem with your car.
My car ran a 12.79 @ 108.8 with just boltons and VT stg 1 cams on 275/15 Nitto DRs....this was my old 04 GT. Search your car over...you have something wrong. Check fuel pressure at load and A/F if you can...something is wrong.
Example is my dads 01 Lightning W/ dropin K&N...and that sucker was running mid 14s @ 94MPH the first trip to the track after he picked it up

...second trip to the track we just let it set and cool down, then with VERY nice a cold weather (50s I think) we got a 14.2 @ 96 or 97. We were like crap...this isnt right.
Well we put it on the dyno and bingo...lean as heck but still made 330RWHP.
Got it tuned with just a 3# lower, K&N round filter and replaced a fuel pump (It was DEAD...only running off of 1 before that). Made 37X or 38X...WHOLE different truck. Ran a 13.1 @ 104 like it should, next trip out in 100% street trim.
Just an example...but point is, your car is NO WHERE close to where it should be. Thats not what you can expect....once you get it figured out you will put down 12s EASY on decent tires.
