MSD Adjustable Low RPM Module
To help out the old 60', I leave the line just above idle "10bolt" but run 4.10's. I would like to see if it would make a nice difference. Currently my 60' is consistant mid-high 1.8's but I don't think the N20 is coming own before the 60' is over.
I realize the risk of turning it on sooner.
