IYKYK. 😂 it’s a good day when these things come out in one piece. Count the little blessings. And yes, we cheated by having the heads on the bench for this. For everyone who has to do this in chassis -bless your sad little hearts.

As promised today we got the SuperCoupe powered Merkur XR4Ti on the rollers to dial in the tune on the Haltech Elite 2500 engine management system.
