I have played with that table and didnt get the results i was looking for. Being a th400 I tried throwing a bunch of spark to add to the main table at the correct coefficient and it didnt help. Whether or not I added enough I dont know. I was trying to get the car up on the converter and 2 step faster to build the boost I wanted to launch at while on the brake on a pro tree. I figured with the bigger motor and the smaller 366 turbos it would build pretty fast. I may look at throwing more timing at it via this table when I get back in and see what it does. thanks for the input.
