it will but you need to calibrate your maf voltage or something for 24smaybe adder will chime in and kick my butt if iĀ“m wrong if you want cheap 30s go find some Thunderbirds SC they haveĀ“em and on the process is not to bad to get a Fuel pressure regulator

If you think you are going to add more power adders or bigger mods in the future, than save yourself some time and just get the 30# injectors. If you're getting an unbelievable deal on the 24#, then take them and sell them online then use the money to buy 30# ones.

If you plan on making 300rwhp, then 24# injectors will be running at about an 80% or so duty cycle. That is just for straight H/C/I work and no supercharger / turbocharger / nitrous. As you start to add to that and go above 300, then you are going to be pushing them to their limits. Personally, when the DC gets close to or above 90%, I switch to bigger injectors. They tend to be sloppy and innacurate when pushed to the limits.

The downside to 30# injectors (or any larger injector) is that they can be a bit sloppy on the low end. But that's nothing that can't easily be addressed with a simple tune. If the MAF is dialed in correctly, then it's just a matter of raising the injector low slope (probably set it to something between 36 and 38.5) and possibly lowering the minimum pulsewidth and breakpoint.Any tuner should be able to bang that out in no time.

In the end, you get a set of injectors that leaves you room for improvement (and leaves you room for a dry nitrous kit.) Plus you know that you won't be running the duty cycle into teh 80s.

If you keep the stock MAF and get larger injectors, then you will have to get a tune that will change the injector high slope, injector low slope, and injector offset. Although many people seem to skip it it's not a bad idea to change the "injector offset vs. battery voltage" function. That will tell the computer what your new injectors are.

If you change the MAF, then you will need to change the MAF Transfer function as well.

well i'm about to throw and 76mm maf on there, and the h/c/i swap is going to happen in like a month. i'm going to need a tune from the h/c/i swap anyway, so when i throw the injectors in there i'll get them to tune for those too. i need to get a 24# sample tube for my c&l maf though right??? (its 19 now)

uedlose

yes you will need the tube for the 24# for your mass air
