A little more info for those shopping EFI systems.... at PRI the MS3Pro Ultimate system was released. This bridges the price gap essentially between the Holley HP which has lesser I/O ports and the Dominator which has a ton of I/O's.
The MS3Pro Ultimate in essence does what the Holley Dominator can do.... at just around the Holley HP price. The Holley systems while not included in their package when you order it.... need (2) 0-100psi pressure sensors for oil and fuel pressure which add another $200+.
I run the HP in n/a cars and forced induction cars can benefit more from running the Dominator setup for boost by gear/time etc. Had the MS3 Pro been available when I bought my systems.... I would've tried that for sure. Plus it is 100% made in the USA with a LIFETIME warranty. They have harnesses premade for the 24x and 58x LSx applications.
