My tuner as you refer, does not spec or use 550s for all applications... He uses the size injector that works best for the power output. Maybe you should call and ask. But everyone has a right to their opinion and in this case, my opinion is that you are wrong.... Which I have a right to have.
Carry on.
PS: Actually I'm getting a set of his 440s very soon because they will fit my upcoming output. So I will be having a set of JCW 380s for sale very soon.

If you take off your blinders and read the facts that are presented in my previous posts, you will see that the "440s" you are referring to are in fact bigger than the OE 550s that we use. Do you know if you are getting his "1st Gen" or the "2nd Gen" 440s?
We have been accused of being in the 'wrong' for the last two years. But the fact that the competition has started selling the same 550s proves that we are very RIGHT

LOL no blinders here, see results very clearly...

The results clearly shows those "440 SRT Injectors" (2nd-Gen) are rated 500cc at 3 bar; "unknown" at 3.5 bar (Standard R53 Fuel Pressure), and 582cc at 4 bar fuel pressure.
Here is a better chart... maybe your beer goggle is still on? :beer

Here are some specifications on the EV14 Injector design as well as spray pattern. The part # to the 550s are 0280158117 and it's not listed on these Bosch Spec sheets (probably due to the fact that they were OEM mfg for Ford Racing)... In any event, for your reference ONLY:

Can somebody say 800cc?
There is a good chance that we might have to go BIGGER than the 550cc Bosch injectors in order to safely produce 250whp or more.
Some more testing data for the 550cc:
"Ducky" was once again put thru the gauntlet yesterday and we discovered some useful data by examining the logs using the FA53 Tuning Kit.
Mods for Ducky: 2006 MCS with MegaMini Camshaft, 550cc, Mynes V2 header + Nvidia exhaust, GP IC and 15% pulley, NGK Iridium 7EIX. Everything else is STOCK.
On California 91 Octane Shell Premium: Power was 206whp / 178wtqe (AFR at 11.6 ~ 12.0, injector duty cycle at 72%).
On California E85 fuel (from Chevron station in Fontana): Power was 227whp / 188.8wtqe (AFR at 11.5 ~ 11.8; injector duty cycle at 88%)***
***NOTE on E85:
1. We can probably lean it out some more b/c E85 has a 100+ octane rating; so we can be in the mid-12 AFR and still be safe. But since this is going to be the E85 BASE TUNE MAP for our customers, we want to keep it safe so they can fine-tune it to their spec.
2. If we lean this out more, we can probably bring the duty-cycle down to the low 80% range.
3. E85 blends vary from region to region and from season to season; so be sure to monitor your AFR while you are doing these power pulls.
Keep in mine, our test car is on the STAGE I Form. If we decide to go with a Stage II head along with the SC Upgrade, then that will likely push us near the 280whp range. At that point, these 550s will surely be maxxed out
Can someone say Bosch 800cc? :crazy: -
RMW 440s => flows 800cc
Someone in the UK had these 2nd-Gen Siemens "440s" flow-tested... see results below (he obtained these from a "trusted source" with the part numbers scratched off):
Please do your research guys... there are a lot of people making a lot of claims, but know those who are actually posting testing data in support of their products. -

We have no problem selling own products on its own merits. In fact, we have been selling the Bosch OE 550s since March 2009 (at AMVIV 6) with dyno graphs and test data to show it's application and performance. Critics were crying foul and that the injectors were too BIG for the R53. Guess what, since we don't "remove or SCRATCHED off" the mfg part number on those Bosch OE 550s, anybody can verify the part number and source it on their own.
After two years of criticizing Mynes for pushing these overly BIG Injectors, guess who is selling it on his website?
You can buy from RMW for $325.00; or pay $300 and get a set from Mynes (or $250 per set if you buy it with the Bytetonik FA53 Tuning Kit).
This is a screen shot of the actual website (taken today):
