So I figured out why my car ran a 13.5 @ 104... I got George Lara to take a look at the tune with HPTuners and we found that both knock sensors are bad (or the harness... the harness is new and the sensors have 95k miles on them, and it has been throwing knock sensor DTCs), and the PCM is pulling timing at WOT. Apparently it was getting down to 18* at WOT due to the 22* peak timing that George had set up a while ago due to the knock sensors reporting [now false] knock. We did a couple of test pulls with a temporary fixed constant 26* of timing and it pulled great with no audible knock. Did the same pulls again with the default settings of a maximum of 22* and it pulled timing and felt like a dog. Also made a few more changes with the fuel trims. Car feels better now than at Invasion, but I still need to get a dynotune from Ryne or George when I can afford it. Have to replace the knock sensors before getting a dynotune or taking it to the track.

Lee, your unwavering dedication is unbelievable. See that bish through to the end, it'll all be worth it the first time you get the time slip you're after! Ever address that trans problem?
Bravo sir, bravo.

Lee bought a simi built trans and replaced the stall with a stock one. He said that alone helped cause we kinda think his other converter went out.
Glad to seeit running though.

I have it listed on Craigslist for $100 and the converter goes with it. If you want it, you better get it soon. It'll be in the desert as of late tomorrow morning. It currently has the truck output housing (F-body length) and slightly deeper truck pan. Guy had the output shaft housing and truck pan on a Strano lowered F-body with a tunnel mount torque arm and the pan has no scratches on it, so he never scraped it.
