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
