Injector Info:
Ford Mustang fuel systems are rated @ 39 psi (2.69 bar), *not* 3.0 bar, so this is the rating for the 24 & 30 lb/hr Ford Motor Sport injectors commonly purchased from Summit Racing, et al. These numbers also apply to Accel injectors, which are rated @ 39.7 psi (For more information, see http://www.mrgasket.com/accelpdf/Injector.pdf, and search Google for “Ford 39 psi”).
Note in the numbers below that, if you “upgrade” to 24 lb/hr injectors that are rated @ 3.0 bar and keep your 2.5 FPR, then you will end up with essentially no increase!
For entertainment, here are some numbers…
New Flow Rate = sqr( New Pressure / Old Pressure ) * Old Flow Rate
STOCK VALUES, CHANGES TO FPR ONLY, AND CHANGES TO INJECTORS:
24 & 30# FORD MOTORSPORT & ACCEL INJECTORS (rated @ 2.69 bar)
Injector FPR New Flow % delta
(lb/hr): (bar): Rate (lb/hr): from stock:
21 lb/hr (stock) 2.5 (stock) 21 lb/hr (stock) --
21 lb/hr 2.8 22.22 +06
21 lb/hr 3.0 23.00 +10
24 lb/hr 2.5 23.14 +10
24 lb/hr 2.8 24.49 +17
24 lb/hr 3.0 25.35 +21
Accel 26#
26 lb/hr 2.5 25.10 +19
26 lb/hr 2.8 26.53 +26
26 lb/hr 3.0 27.46 +31
30 lb/hr 2.5 28.93 +38
30 lb/hr 2.8 30.61 +46
30 lb/hr 3.0 31.69 +51
Additionally, here are some numbers if you use 24 & 30 lb. injectors rated @ 3.0
24, 26, & 30# (brand??), et al (rated @ 3.0 bar)
Injector FPR New Flow % delta
(lb/hr): (bar): Rate (lb/hr): from stock:
21 lb/hr (stock) 2.5 (stock) 21 lb/hr (stock) --
24 lb/hr 2.5 21.91 +04
24 lb/hr 2.8 23.19 +10
24 lb/hr 3.0 24.00 +14
26 lb/hr 2.5 23.73 +13
26 lb/hr 2.8 25.19 +20
26 lb/hr 3.0 26.00 +24
30 lb/hr 2.5 27.39 +30
30 lb/hr 2.8 28.98 +38
30 lb/hr 3.0 30.00 +43

Search "30#", "30 lb", etc. for info on upgrading. Also search "resistor".
Ford Motorsport (Bosch) & Accel (may be re-labeled Bosch??) 30# injectors fit. Have seen sets of 8 for ~$180 on 'net (look for Mustang performance sites). SPG9 charges more than that for 4.
---------------
Ford Motorsport 30.0lb/hr (Part no. FMS-M9593-B302)
Accel 30lb/hr (ACC-150130). I believe the 3rd digit in the p/n reflects the number of injectors. So, provided they sell sets of 4, which I don't know, I assume the p/n would be ACC-150430.
According to a Jeep perf. site I ran across, Ford Motorsport 24 & 30# injectors are rated @ 43psi (3bar).
