Help Choosing Holley Sniper EFI

93gtmustang · Jun 17, 2024

I'm ready to upgrade my EFI. Looking for some input on which package to go with.
I like the 4-barrel type. Looks like the way to go for a drag race only car?
Thanks!

No no no no snipers period . If you have to have a 4150 kit you need a term x 4150 stealth unit keeps the ecu in the car and is light years better.

BUT -

Do the terminator x mpfi kit. The 4150 kit is limited depending on what you do . The standard mpfi kit will take you wherever you want to go and then some.

Thanks for the info.
Do you have the terminator x mpfi kit in your car? If so, was it a pretty easy install?

I was looking at the Mega- Squirt. Seems like a way easier install!

You are going to have to give us a lot more background on what the car currently is, and what your goals are.

1993 Mustang Drag car. Stock Fuel injection. Ford Racing GT-40 Crate motor. 345 Flywheel hp. Built Dynamic racing C-4. Bunch of suspension. Cage. The next plan is to upgrade to Trick Flow 11r heads that will put me about at 411hp flywheel. Looking into engine management to accommodate future up grades and changes. Just getting my ducks in a row.

I have the next step up which is a HP mpfi kit since about 2017. I didn’t find it hard at all but I don’t find wiring hard .

I’ve done probably over 6-7 cars now with them . I’ve used universal harnesses and the ford specific harness. They aren’t bad at all to do in my opinion

Easier install (provided your wiring is in good shape), but steeper learning curve when it comes to tuning. Holly has a more difficult (and costlier) initial install, but tuning will be easier and tons of support.

That's good to hear! It seemed complicated to me, but....
