with those mods...you have maybe 245 to the wheels? not anywhere close to 300...except maybe at the flywheel.

and it does improve times a fair amount...without the gears you prolly wouldnt run under maybe a 14.3ish?

You really need to get an exhaust, some kind of o/r mid pipe or at least a catted one and possibly some headers. Cause right now with your mods although they are helping you its still like blowing into a straw cause your exhaust is so restricted. Do that and youll see some better times

If it helps,

My car is an auto and i have the following mods

4.10 gears
Accufab 75mmTB and Plenum
MAC CAI
SLP x pipe
Borla Catback
Diablo Predator

I was dyno tuned at 249 RWHP and about 300 FTlbs of TQ

I ran the 1/4th at 13.70XX @ 98.8XX Mph on stock street tires on a 80 degree day

i went to the track last wednesday and it was hot and muggy. everyone was running like crap. with stock tires and the mods in my sig i pulled a 14.1@100+, i did that 5 times in a row. my best time was stock 14.065@98 but that was with perfect weather condition. last wednesday when i went i was spinning all of first and second, without sticky tires it doesnt matter kind of power you have. i know i have alot more power now with my mods, but i cant get the power to the ground.

Is that a slow time on average with all those upgrades?
