I have been in touch with Bison, I sent him some pictures of my turbo, also looking at what he has, suggests. Once I pick the turbo I will contact Dusty. As for rpm drop mine does drop between 500-800 per shift.
says it should have went 128 mph so how does that determin percentage of slip ? sorry I tuned the car with scan master only. 3.42 gear no idea of rpm 28 inch tires
You have to know the trap rpm to calculate slip. No rpm drop means the car is driving through the converter or the trans is shifting to early. A stock bottom end car will need to shift at 5200 rpm or so which requires a tight converter.
