Very confused, need help!!!

Okay so we went to the track this past weekend, and lets just say i am very disapointed. My car, and my friends car have pretty similar set ups on a 95GT, and my car isn't running like I want it to, or should be running. These are the set ups, and times.
My Car:
306, S-Trim w/ 2.85" pulley, AFR 185's, RPM Intake gasket port, 70mm Tb, 80mm MAF, 42lb inj., NX274HR cam retarded 4*(.555/.570), BBK LT, O/R H, MAC Catback, 5 spd, tremec 3550, 3:73's, full weight GT 12.23 @ 113mph

His Car:
302, S-Trim w/ 2.75" Pulley, TFS High Ports, Holley Intake, 75mm TB, 80mm MAF, 42lb inj., TFS stage 1 cam straight up, MAC LT, OR H, MAC cat back, 5 spd TKO, 3:73's, Interior ripped out, and just the driver seat. 118 @ 11.96

I was thinking the Intake, and TB on my car is really hindering my set up, but can it really make that big of a difference? Any help would be cool. Thanks.

Could b in the tune..But definitely not the throttle body size...i make way over 600rwhp w/a 65mm.....

what kind of tires and 60'. You should be in the mid to low 11's I'd say with those setups on slicks.

Maybe your spinning real bad. Are the tunes or timings a lot different?

One may be getting out of the whole a lot better.

well I am thinking it is in the tune. I am going to try to tune it at the track today, hopefully it helps.

If you can't find anything wrong in the tune post back. Is it a complete mutt below 4000? DId you degree your cam in then retard it 4*? I'd install it per comp's reccomendations. 108* i think on that one.

Where is your timing?

well guys I think both your set ups are out to lunch my old 94 cobra with ported gt-40 and bigger valve ,stock cam retarted 6 degrees,ported lower ,untouched upper,70 mm thr,42 lbs, forged bottom end,shorty headers off road h-pipe,stock cobra cat back,355 gears,445 rwhp 11.72@121 mph.drag radials ,315/35/17,pump gas. i think you better tune the cars .
