Seems like the "best" current bolt-on EFI's are still iffy. Friend works in high end shop that uses EFI on most builds. Last one was simple no-brainer build. Way overkill engine shop and Holley Sniper was not right on dyno. Holley was even present. Holley sends out another new unit and it worked. But still nothing impressive at all on dyno.
I'm sure when the magazine article is published, the EFI issue won't be mentioned. :rolleyes:
