I want to improve this combo

The Modifications to the car are as follows:
95 Explore GT Short Block. ( Same As 93 Cobra)
Ported GT-40 iron heads with 1.84 x 1.54 valves,
Steeda #18 Cam 220/226 .480" (.513 with 1.73 ) on 112lca
Steeda 1.73 Bolt Down Shaft mounted rocker arms
Ported 93 Cobra intake
65mm Throttle body,
75mm Pro-M mass air meter,
24lbs injectors,
UPR Adj reg & stock fuel pump
5 speed computer with UPR/autologic chip
Hedmen 1-5/8" Long Tube headers,
2.5" UPR X-pipe and 3" Borla Xr-1 Mufflers Dumped

This combo in a 5-speed put down 320rwhp @ 360rwtq went 12.39@109 on drag radials
Same combo with C-4 and 3800stall went 12.50@108 on drag radials
The only accessories not there was the smog and the power steering

Now this combo is in my daily driver with an AOD w/Low-gear set - 3.73 gears
Lentech 12" SS non-lockup converter (stalls around 2200)
Lentech street terminator valve body.
Oh and a stock fuel pump
No dyno or ET's yet
The car doesn't feel as strong as it did in the other car
i know the AOD/2200stall and having power steering back are soaking up power

My question without changing the whole combo or a power adder
whatwould help this combo out what things would you change
Oh and i'm trying to keep the cost low

I know i need a fuel pump but would a big pump make that much of a differences

Timing is set at 16* fuel is around 38psi
Ignition is MSD pro billet distributor, 8mm Taylor wires and NGK TR5 gaped to 38
The computer is an A9L out of my brothers 91 lx coupe 5-speed he had an Autologic chip burn for this combo years ago.
the car its in now is also 91 lx coupe
The only suspension upgrade is 5-lug conversion and new sway bar end links

i will be putting a 255lph pump in it soon,
when it had the stock engine in i had a 100shot kit on it.
No if i use that same kit i know it would hurt the engine without the pump.
but the longer i keep the stock pump the long i go with out spaying it.
