My current mods are simply a HYPERTECH II 93 octane tune and a K&N filter with the silencer removed.

I was considering installing the Ford Racing 24lbs. "matched" injector set along with a C&L MAF housing.

My question is, will the addition of the 24 lbs. injectors mandate other mods, or will this mod work sufficient by itself?

I appreciate any assistance. THANKS ~ !!!

Larger injectors are used to support other mods. Switching to larger injectors will not make power by itself. The flow matched injectors will decrease air/fuel variation among cylinders, but I do not think it is worth the cost for a mildly modified engine that is not tuned to the breaking point.

+1

You will not gain anything by increasing pressure of injectors without having something that will actually use the increased pressure (Supercharger).

you could put 42#hr injectors and still have them flow at 19 or 24. But you wont really need better injectors till you get more mods to the motor.

and our 19#hr injectors can be maxed out quite easily by doing all bolt ons IE: Headers, CAI, cat back, ect ect. so going with 24# injectors along with a good tune would be fine. but you would do well to upgrade your Fuel pump as well.

Everyone who has commented is correct, you could not begin to maximise the use of the 19's you have now untill you did head work and cams.

Special Thanks

Gentlemen,

Thanks for helping out with all the great advice. I'm sure I got the answer(s) I was looking for.

As far as a "good tune" goes, I am starting to wonder just how much our stock cars can be tuned ... (???)

After all; without adding any additonal power by going with an SC, etc. we still only have a 281 CID engine, right?

The tune I am using now (the HYPERTECH tune) has really woke this car up. I had no idea that tuner would bring such a noticeable change.

I am contemplating adding a BBK CAI, cat-less H-pipe, and maybe some Ford Racing shorty headers followed by a 3.55 or 3.73 gear.

After these mods are done, is there really a better "tune" to be had, or will these mods sufficiently max the HYPERTECH tune that I have now?

I ask this with adding that this vehicle will never see a drag strip and will be used mainly as a "road car", however in Houston (and/or Dallas/San Antonio/Austin traffic) it doesn't hurt to have a real good gear every now and then, Ya know?

Thanks again for all the help !!!

Hypertech Premium Fuel Tune: Great addition , I agree that it really wakes up the Bullitt.
I bought the Max Energy part # 42000 from Hypertech.
The salesman logged into the Hypertech site and loaded the Bullitt data into the programmer.
I installed the Premium Fuel update, and did not change anything else, and I love the difference.
Once I ran about a quarter of a tank through it, after programming, I noticed the improvement.
Immmediately after programming, I stalled it 3 times taking off from a stop, on my way to fill up with premium, and I heard some ignition knock a few times. After the premium fill and a quarter tank of use, IT IS ALL GOOD. Glad to pay for premium now.
