    Where was the oxygen sensor when you were on the dyno? Tailpipe? If so, that can read lean when you're fine.

    yeah it was a sniffer style wideband. i did not reset the pcm. i think im just gonna leave it at 40 for now. im working on getting a fuel pump (walbo gss 317) and i just bought an underdrive pulley. i still think the dying fuel pump is a big part of the problem. it is the factory unit with 227000 miles on it.
