PTC converters switches hands

Have two converters by them, very happy with both. I did fill out the spec sheet for the last one sent it in. I got a five word email response that told me they had not read the spec sheet. “8” 5500 stalll,$950 + shipping” Went through CRT to get it and it flashes to exactly 3500 rpm. Which is what I wanted and can use. I understand you take my little tire out of the equation and an 8” stalling at 5500 might be the one, but I was VERY specific on what I was doing with it.
5500 stall converter that flashes exactly 3500? I assume you meant it flashes at 5300 in your application.

I had PTC spec my converter and they came up with 5800 stall. Problem is, it flashes at 5000 which isn't what we discussed. I did finally get in touch with Kenny. He found my spec sheet and told me to send it back and he would fix it.
