Of course I installed LT's and 4:10s blah blah blah... just like everyone else the 4:10s made the biggest difference in ET but the headers ehh not so much. So my question is how much of a difference will a tuner tuned by the right guy make in my ET. Keeping in mind I'm lucky to run a 13.9 lately and has never been tuned.

just drive it like u stole it.
can some explain powershifting.... isnt it when you keep the gas pedal down as you put the clutch down and change gears?

i just shift really fast and run in the 13.8s even with shitty tires
yeah you should really lower those 555rs down like whitestang was saying. my car is on the stock 245 tires right now and there bald i lowered them to 25psi and i was dropping it at about 2100 and pulling off 13.8s and 13.9s just find the sweet spot for your set up.
u have to be shifting to slow.
my r/t was a .186
60' was a 2.146
1/8 was a 8.909
1/4 was a 13.892 @ 99mph

even still shifting slow if u can lower the psi in those drag radials and get some good 60' times you should cut off at least half a second.
