So I am a born again on road guy, last car I had was a pro2 about 15 years ago. I am on the fence about this car because I do not really understand this gearing problem. Running a 13.5 am I going to have a problem with gearing? Is there a better car for parking lot racing?

Well, you can always use a lighter lipo pack than everybody else like the thunderpower tp4300-2spr65d(240grams) $89.99....
I was about 20 grams away from minimum weight for TCS racing with the TB-03. That was with a lightweight NSX that is now discontinued. A Protoform LW speed 6 is another 30 grams heavier. That puts this cars weight 80 grams over ROAR minimum...anyway, that's a bunch and that's my concern. I'll know more when I get the car built 100%.

Built the TB04 gear diff tonight. Not bad. Need to upgrade the internals though.
TAMIYA TB04 hop up gear diff parts:
54540 metal gears (I don't see it for sale yet)
54533 metal cross pins (available now)
Built and installed. Just not installed in a TB04 though, haha.

Just got home from the Speedtech Race at Tamiya Raceway where I ran the TB04 for the first time. Overall, the car was consistent and very easy to drive with little to no setup work. I qualified third and finished third in a field of very fast racers with carbon cars as well as one friend who was absolutely in his own zip code, planet, galaxy, cluster, you name it...we were basically racing for second 
Here's a video of our second qualifier. This was the third battery pack and second run in full race mode. For this run, I used a different set of tires, causing the car to develop a moderate under steer, and ended up losing a position by choking on the second to last lap...fail

What gearing were you using for that race?

With a car like that, it was a really fun run. That being said, Duy was really in another time zone. Sometimes you're the bug and other times your the windshield. His motor and chassis homework resulted in raising the bar in terms of fast laps for 17.5 at the Tamiya track with a 13.4 and averages in the mid to high 13s. That's insanely fast and his runs were impressive.I was geared at 3.56 with an R1 motor and battery. I was originally planning on running a Reedy Mach 2 and TP battery at that ratio, but Steve from R1 works was gracious enough to lend me a few goodies to test. Thanks Steve for the rocket fuel. Holy crap it was fast
Here's a photo of the car before the main:
