Just got back from the dyno :(
My best was 211.9 hp and 224.1 tq
. Mods 2.5 b pipe, 2.5 wsp y-pipe which now I'm a firm believer it does nothing, UDP, and homemade pop charger. Well I'm slightly ****ed and thinkin of removing the wsp y pipe and redynoing. I was talking with a few z-28 guys and one said he was off 16whp from the last dyno with nothing changed. Well I don't know but my power didn't drop until 6200 which I was surprised by that. I will try and scan the sheet monday.

I too went with Matt to the dyno today. My car, 2k2 6spd, put down pretty much identical #'s as Matt's dyno. I'll scan it and post tomorrow. My mods include: Frankencar Intake w/ Apexi Filter, HKS Rear Exhaust, RT CAT, and UR Pulley. I'm also very disappointed by my #'s, in fact I'm shocked. I'm heading down to Precision Dyno(different dyno) next weekend to try again. I'll be sure to post the results.

Here's my crappy dyno:
As you can see my best pull netted 211.0 HP and 229.0 LBS. Torque. I strongly feel something is 'not right'. All runs were pulled in 4th gear. Other org members with similar, or the exact same mods, have posted dyno #'s way higher than mine. Like I said before, I going to a different dyno next weekend. Blubyu2k2 and BJJ, you're welcome to join me if you like. If not then I'll let you know the results. Yes, this is starting to bother me.
Also, my car is running extrememly rich at higher RPM's. It's better than running lean however if anybody has any ideas on how to better my air/fuel ratio I would love to hear them. Thanks.

Seems like the dyno may not have been accurate.
Redynoing somewhere else when you get a chance.

That graph actually looks pretty good. You're making over 200whp from 4800 all the way to 6300 rpm. The averages mean alot more than the peaks.

If you guys go to Precision dyno, don't pay too much attention to Tom. He can be very annoying sometimes.
One thing you guys should do is have him hookup his multimeter and monitor your injector duty cycle. I may attend just to see that.

I'd like to see what numbers you get when you go somewhere else. And I won't post any more comments about the Y till then
To bad you guys aren't a little closer I'd go with you and get mine done also. I live in NE Atlanta and I'm planing on getting mine done soon. It will be nice to compair the numbers with mine having a stock exhaust.
I'm waiting till we have a couple of companies that have headers to see what kind of numbers come out'em before I do my exhaust. Until then I may get a new B-pipe W/res. and mod the stock muffler. I also like the way WPS, or who ever makes it, has done their Cat but that will be something I do later on with what ever headers I end up with.
Good luck with the new dyno.
Oh yea I meant to ask is 3rd gear the closest to 1 to 1 in an auto?

If you have an auto then you should dyno in 3rd gear.
If you have a 6-speed manual, then you should dyno in fourth gear.
Tom is a good guy at Precision. He dynod my SS many times and I was always happy with the results. Using his multimeter and wideband O2 will cost you more money.

Are you guys concerned about the ultimate numbers? A dyno is a tool to measure your performance gains and losses. It's not made to compare your results to someone else 8 states away. Don't get so caught up in the true numbers. You should be concerned about the gains and losses and changes in the power curves.

I don't know why you're so concerned nor why you believe your mods are doing nothing for you. Look at your timeslips and notice how you're going quicker with more modifications.

There must be more to this story.
