New Converter, Different Shift Points?

I ran the tighter converter with the taller tire and the 60" to 330' was better, the 330' to 660' was better but, loses MPH in 1/8th mile and the 1/4.


Then, I swap to the 1.4" shorter tire and the 60' is better than ever but, shift recovery is worse than the same converter with the taller tire.


I'm not hearing what it's trying to tell me. I would think the shorter tire would recover on the shifts better than the tall tire. Unfortunately, my last race was all 1/8th mile so, I never ran it out the full 1/4 mile. Looking at the MPH at the 660' doesn't indicate it was going to find anything in the last 660' but, I could be wrong.


I called ATI about sending one of them back. They told me they would be guessing if, they tried to make either one of them better and suggested I just use the one the gives the best ET.


Thanks for the responses, so far.
