shouldn't I be running faster

[clearwaterms]

Last Saturday, i went to the track. I ran a best of 13.9. Last year I ran a 13.3 with the same combo, save for the fact that we were on Drag Radials and a stock trans. Since then we put a new AOD in with a PI stallion converter and a trick valve body. Now I know that having cheap GT+2 tires are killing the 60 ft. like a 2.45 with road race springs. Also Im hitting like 6000 RPM's at 1100 ft. and am bouncing off the rev limiter as I cross the line, I think this is slowing me down. I still am running 13.9's at 102~103. Last year I ran a 13.3 at 103.45 crossing the line at 5300 RPM's, could the Converter be making that much of a difference? Is it just that I am a rookie driver? Here is the break down of the car...

89 LX convertable
A-Trim pullied to 10#'s
24# injectors, 73 mm mass air, 70 mm throttle body
AOD tranny custom built by TSI with PI converter, Manuel/automatic valvebody, lightened internals
4.10 gear
stock sized rims and tires
drop springs (steeda springs)

I plan on adding a new cam, intake, and porting and polishing my heads in the next two weeks, what will be the impact on the car now?
