Today was the big day, but it didn't go like I had hoped. Here's what I went up with:

H23A1 with 176k miles, 175 PSI on all cylinders
I/H/E
Magnaflow cat
12lb flywheel
64mm TB with matched intake
Crower stage 1 cams with adjustable gears
Fairly heavy 17" rims (didn't cheat and throw my light weight 15's on for the day)

I went down there with Team Blindside to tune the car. To hook up the wideband, we had to remove my muffler, so the videos I post later will be pretty loud. First two runs went fine, just establishing everything. Next run they tried to lean out my AF, which threw a CEL as soon as they touched it. There were unable to do any ECU tuning because of this. Right now I have a chipped P14 with an approximate chip. Anyway, after we gave up on that, we adjusted the gears, which in itself leaned it out a little, and gave me 15 more HP on the top, as well as a much beefier midrange (which was my goal, we could have had more on top if I wanted). In the end, I had 137 HP, 138 TQ with an AF of about 13. Now, this was on a Mustang dyno, so it's 17% lower than a dynojet. Now, just before we pulled it off, we did one last run with the muffler on back on and I lost almost 20 HP and TQ. So I learned two lessons today. There's a reason no one chips the P14, and Pacesetter exhausts really do suck

Nice numbers. Gotta love H23 graphs.

160whp on a Dynojet? Not bad at all.

its good to know that after 175K+ the motor is still healthy.
gotta love Honda reliability.

too bad I can't say the same about my h22a4 with 160K its compression is down to 155psi across all cylinders. But I blame the nitrous not the motor.

This makes me curious to put my H23 on the dyno, 127K miles.

Not the whole catback, just the muffler. Either way, I ordered a twin loop. Not the best performer, but better than what I have, and a much better sound

When I go to dyno, I want all my stuff on because I need it as accurate as can be. I'm not gonna be racing without an exhaust or anything like that. I'm making slow progress. I'm getting a 4bidden short shifter next week and HOPEFULLY the week after, resonator cause my exhaust is ****ing annoying.

Long awaited video. This was the run with the muffler on. It sounds terrible. Im actually driving around without it now and although its much louder, its not as raspy :P

that's why you stick with dc exhaust
