I have always had good luck with PTC. Kenny Ford, the owner races a Mopar door car.
Had an ATI once too, no issues with it at all.
No matter who makes one, giving good intel on what you got going on makes for better chance of them getting it right. Be extremely accurate.
Guys tell the convertor Company they have a fire breathing 630 horse smallblock, and they really have a smogger headed 318 with single legged 2.76 gears out back... they aint gonna get the convertor right....
