A used C5 or new WRX is starting to sound awefully good right now

I suspected the dyno at first, but Brian's Z pulled 244 RWHP just minutes later. Thats on the higher side of 350Z dynoes I have seen. This leads me to the conclusion that the dyno is accurate. I am just clueless to whats wrong here. I changed my plugs, cleaned the injectors, cleaned the MAF sensor, and checked my flex. I cant think of anything else besides the coil packs being defective, but my car makes good torque.

1/8: 9.638@73.2
1000: 12.508
1/4: 14.915@94.72
The weather was in the high 30's IIRC and I removed the jack and spare. I had a 1/4 tank of 93 octane fuel.
I had ran a best of 15.0@95 previously at RT66 IN 90 degree weather and very high humidity last summer.
The car is clearly not making power up top....Take a look at my dyno. My VI is clearly working, thats the funny thing. I heard it switch over on the dyno and my friend watched it actuate.
FYI....My brother in his auto 99' ran nearly the exact time I did and I30MikeD ran a 14.6 that same day.

What I'm seeing is a car that's lacking lowend power. Your 6.315 isn't terribly quick even though you came off the line with a decent 2.27 60 foot. Your 1/8 is okay, but your trap is a little low (73mph). But looking at your final 1/4 mph of almost 95mph, your car is gaining almost 22mph. That's STRONG. What do I think the culprit is? Those damn stock 17s. Those 55lb tanks kill your initial acceleration. Next time try and run on some 4th gen 16s or try and find a 40lb 17" combo. My ASA LS5 17" combo with 235/45s weighs in at 41lbs or 1lb lighter than my stock 15" combo. The LS5s were $1100 from the Tirerack. Cheap and light 17" combos are out there. A guy in the KC Maxima GAINED .3-.4 and LOST 3mph going with those heavy 2K+ rims.
