can i use 24lbs fuel injector on a stock....

[jaydog5.0]

.. motor with mild upgrades? and if so do i have change anything else?

If you mild upgrades include just bolt-ons, you can keep your 19lb injectors no problem

Yes, you can use the 24lbers but you need to change to a mass air flow sensor calibrated for them. The stock one won't work to hot for ya...good luck!

Gotta do something with the maf/computer.

You don't really need more fuel if air flow has not increased though.

Hey - I got a similar question - I have 76mm C&L MAF, 70mm t/b, Edelbrock Peformer 5.0 intake, E303, 1.7's, lightly ported exhaust side of E7 heads, MAC equal length shorties, Flowmaster catback, K&N cold air kit, Crane coil but stock lower end - would 24# injectors be the next thing to make it quicker off the line or am I still fine with 19#? I will have a 190lph pump in next week too.

Any of you guys might consider an adjustable fuel pressure regulator especially when 24#'s and larger fuel pumps are used.

got an AFPR Kirban unit - what about 24# injectors vs. 19#

Take it to the dyno have it tuned see if ur running out of injector, easiest way to tell if you need the 24's or not.
