MSD Timing twister? MAP sensor boost retard
http://www.msdignition.com/new_produ...ngtwister.html
Reminds me of the days of the 6BTM on a mustang. You can dial in a retard of .1 to 1.9 per pound of boost. Do you think it has it's merits or is just better to set a timing table based on RPM?
I've used it for a year with a 3bar sd tune and 17psi....great tuning system for boost.
