There's a few other things to take into consideration here too.
In reading your post and sig, it appears that your car is very heavy. The T-Top cars already weigh more, per the extra bracing and glass tops. Then it appears you've also added to the problem with a big stereo system. I've learned over the years to sacrifice the tunes for the ET's! Anyway, you're already a little handicapped per the weight of the car issue. Hopefully you yourself don't weigh more than 150-175.
Back in the early 90's, the PitBull chip was all the rage. It was the best upgrade at the time, but that is ancient history now! I don't think ATR has changed their chips in a long time, and today's fast cars are now running low timing and high boost. The PitBull is notorious for higher timing levels, and often prone to detonation. Detonation = slower ET's and broken parts! However, you aren't going to run worth a flip with your stock chip either! Back in 1992, I went 12.61 with a stock fuel pump, stock injectors, PitBull Street chip, and about 20psi. However, it was a 50/50 mix of C16 and 93 octane. I wouldn't recommend it now!
This was also when it cost $250+ for a good external fuel pump upgrade, before we had these wonderful Walbro $110 intank options. With pumps being so inexpensive and readily available these days, it should absolutely be the first thing you do, before playing a game of Russian Roullete with your car, and hoping you have enough pump to support it! By the time you hear it clattering audiblely, it's often too late. If by chance you decide to go ahead and run it, PLEASE be conservative on the boost (18psi), and run a good mix of high octane race fuel. If you don't, then you'll have no sympathy from anyone on this board when it pops a head gasket or grenades a ring-land!
One final step I would recommend, for good measure, would be to get a volt meter and check the power output at the pump. It's easy to check, and don't be shocked if you see it reading extremely low. If it reads low, it should be another red flag for not taking it to the track until you upgrade the pump. The stock injectors will get you mid 12's with no problem, as long as they have a pump that can feed them. I also recommend buying that set of 36's from Red, if you can afford em'. They're a great first step upgrade, and will support up to mid 11 ET's.
