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 guage 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.
