I suppose you can pull your O2 sensor(before the CAT) see if that makes a difference. Sounds similar to a clogged CAT, but Idk with the shifting problems.

No idea... I lost first gear and major slipping in trans ... and a boost leak on manifold... 4 psi peaking at 5k rpms and car ran a 14.013 @ 103 mph. After a new trans and a motor rebuild with some upgraded internals I blew the seals out on first time i hit boost so i said F it and sold everything. then the built trans i had in grenaded when it was stock.

What would that show? keep the sensor plugged in just pull it out?

the way i had them on before. If you dont mind posting the diagram i could double check. But i still dont see it being the issue but i won't overlook it.

If your cat was clogged it would relieve the back pressure. If it is clogged you should notice some restored power. Yes, I would leave it plugged in, just tie it out of the way. Don't drive too long like this, just enough to check.

Really you should drill a hole instead of removing the sensor, but if the CAT isn't the problem, then you have a hole that needs welded shut.
