You're probably due for a new set of plugs now. If the car takes longer to start than it used to, plugs would be a good guess.

Running like utter hell?
Care to explain that?
Is this on start up?
When it is warm?
Etc.
Be as specific as possible, I can not guess from the little info you gave

I experienced heat soak with my accel coil packs and I developed major misfires.
I went back to stock coil packs and I have been fine since.

Check the plugs, tell us the color and gapping.

WELL ALL YOU OLD SCHOOL GUY KNOW ME (MIKE MALLOY). i'm thinking with all the mods i have, my car should be much faster. i haven't taken it to the track in awhile. off the line the car is a monster, very very faster. this is due to the 3000 stall converter and zero wheel hop. once i hit 60 mph, the car is a dog. i don't know if the tranny is slipping or what. i'm thinking of doing some serious weight reduction. i have all the bolt-on's. i'm thinking also that my car is really out of tune. i do have autotap and the maft+, but right now i have no laptop to see how te car is running.

Hard to say. Is it dogging just na, just when spraying, or both?

Could be a clogged cat. Could be knock retard taking the timing down. Could possibly be plugs or weak coils. Without seeing your sig, I don't know if you've swapped cams or not, that could be a factor. Some autotap info would help. With 20k on cold heat range plugs, they could be fouled, which would give you a weak spark up top.

Auto tap or wide band dyno time.
When you get seriously mod'ed you need to spend some time tuning it
