SGI-5 question
Well, the T-56 is finally going in, as well as a posi 3.73. I was wondering is the SGI-5 is capable of converting the pulse rate down from 40,000 to the 4,000 needed, as well as recalibrate my speedo for the 3.73s. Thank you in advance.

Yup, that's what it does. It can also convert to 2000 pulse output for those running the '165 MAF ECMs. It's pretty configurable to accomodate varying gearing, shouldn't be a problem for your 3.73 rear.
