Impressive time! Take it for what it’s worth I was curious if JB4 accounted for the ethanol in the pump fuel. Terry recommended putting in 4-5 gallons of E85 per tank. So basically they did not.
Add a few gallons of 100 octane or appropriate amount of Torco or VP race gas additive each fill up. Kind of a pain but an alternative where 93 is not available ie AZ and California
Has anyone seen this kit. I would think it would work and be beneficial in the Emeria i4 platform.
