get your car tuned/or diagnostic check. something must be wrong to see 15+ consistently, unless you had a bad run. ~1600' is not enough altitude to run that slow.
lots of good suggestions in the other replies, but to gain .5-.7 seconds you need some serious improvements, or determine what is wrong with your ride.
just for reference, i ran my car once at the 1/4 mile track nearby (~500') on a hot summer night and saw 14.3 @ 98+, with a 2.1 60'. i'm essentially stock.

I would get a tune but they seem awefully expensive for these cars...

actually it does make a difference... hold 3rd the whole way - you'll need to shift near redline each gear to make it through in 3rd... if you still have 3.3 FD you'll be fine... if you have your rev limiter bumped it will be easier.

I heard that if you put your car in neutral, press the brake down, rev the motor past 5k, then put the car back in drive and don't let the brake up. Then when you powerbrake it tricks the computer and the car will launch harder. Let me clarify something though I'm not saying to neutral drop your car. Hold break-rev past 5k-holding brake after the revs come down-put into drive-powerbrake to launch...

all have good points.
few things i want to add is that DA 1100 auto G should easilty be in 14s and trap atleast 95 mph.
Clean you airfilter/maf sensor/throttle body.
Do a fuel treatment and run with 101 octane for one tank to clean crap off.
Make sure have 91+ octane gas in it.
No one should be in the car when u are running.
Back in a day I was running 14.9 with my stock G with over 4000 DA in palmdale, CA.

OP - FYI:
I ran a calculation to correct my 1/4 mile time and speed for my 1937' DA. for your reference, the corrected numbers were: 14.0 @ 100.2mph. The track times were 14.3X @ 98mph (465', 77F air, 30Hg, 64 dew). this may help you get a baseline of where your car should be performing.
you can find a good calculator at:
http://www.dragtimes.com/da-density-...calculator.php
this is what their calculator estimated your FLYWHEEL h/p at:
1/4 mile time:15s
Trap Speed:92mph
Weight of vehicle
with driver (pounds):3600 (i used my vehicle/driver weight in lieu of yours)
Horsepower @ flywheel = 214.81 HP (uncorrected numbers used)
...so something is not right...
