Kind of tough to say how low end is with a turbo auto car. I've made 15 psi @ 3200 rpm before with the old converter but it took way too long on the 2 step. Now with the PTC converter it flashes to 3700 on the trans brake which is 1200 rpm more than the old converter did. The thing with a good turbo converter is when the boost comes in it slips up to about 6000 rpm and starts coupling hard.

In this graph I'm over 800 hp from 105 mph to where I let out. I held it out to 170 mph a few pulls.
