Take a FAST EZ-EFI.

Then get its equivalent TB-EFI system in the Holley EFI line-up.

(Neither with fuel pump master kits)


Presuming you're getting both @ the best price on the internet, what is the difference between the 2, dollar-wise?

Has any one comparison-shopped the two, just on price? :confused:

Thanks for providing your best approx. guesstimates in your reply. :beers:

====================================

(An EZ-EFI + an Air Gap is now how much less $$$$ than its nearest similar system via Holley Avenger EFI?)

The Avenger Holley kits all come with fuel pumps.

The HP Holley kits don't come with a fuel pump, but need a laptop.

THe EZ doesn't and has the "master kits" as you say...

So its hard for a direct apples to apples.


I'd say get whatever kit you think is best for your needs.

Looks like you've already narrowed it down to two systems that'll do the trick for ya.


The EZ-EFI is more affordable out-of-the-box, ready to crank & go, & fine for 98.7% of non-racer pump-gas street/strip peeps.

If the project is in the other 1.3% that requires additional capabilities, spend the extra-bucks & get the Holley-EFI.


Price shopping the Holley-EFI is easy. For now, it's within a few bucks of being the same price everywhere, depending on shipping. Maybe a few bucks off MSRP, maybe not.

Prices on the EZ-EFI can vary, depending on source, depending on promotions, going-out-of-business sales, liquidating product lines, inventory, etc

Thanks for all replies! :beers:


Doesn't the Holley EFI have spark control,

and the F.A.S.T. EZ-EFI does not?


If that's correct, it'd be worth paying a bit extra for the Holley EFI. :yes:
