converter slipping

the converter was more for strip than street hence the hi stall. I went over my specs with Lane at ptc, but I had told him 3.5 gears. I have put 2.75 gears in for road brke in miles not thinking it would have the effect it has.
the fluid seems not hot at all after 3o mile drive, but will put a temp gauge in to be sure.
at 3500-4000 the boost and converter seem to come on at around the same time and things really get interesting. loving boost already.

That might be the issue right there, your not staying up in the power band like you were, and the converter is probably slipping. I would for sure add a temp gauge.

Did you add the boost after you got the converter?

I'm just spit balling here, but like I said, I swear I read that with a turbo you don't need the high stall.
