Injectors

guys,
I need a very quick response, so I am here.
Recently, I have my Ford T-6 installed a tuning chip that increase maximum rail pressure of about 10% over standard. However, this extra pressure keep drainning off. This means, there must be a rail pressure relief valve somewhere along the high pressure fuel line, that needs to be strengthen (just like the older models), but we just don't know where it is.
As a system standard, I am sure that all commonrail diesel must have the pressure limiter valve somewhere, but most new models do not have this valve on the rail.
Anyone could help me out about this relief valve location?
Thank you very very much.

Alright, I get enough white smoke on the start now I think its time for new injectors. Its got 198,500 miles and to my knowledge never had them changed, I bought with 186k.
I was looking at standard output ones for $190, and then there are "marine" ones for $210 and then there are "40 hp" ones for $217. I heard that the "performance" injectors are garbage, but I also heard from some people that you can feel a difference in torque.
What are the differences in the three injectors?
And, for 20-27 dollars more would it be worth experimenting to see if these non-stock injectors are any better?
Note: that it will be on a stock turbo setup, with cold air intake and soon to be 4" exhaust, if that makes a difference.
Here's where I'm thinking of buying:
6.5 injectors - Filter Results
Thanks.

have pop pressure set to 2200-2300 psi +-10%.

There is no benefit to marine injectors unless you run the mechanical DB4 marine IP,the IP is the bottleneck-not the injectors.
Stock injectors have the ability to flow more fuel than the IP can provide,don't get sucked into the +40hp claim because it is not gonna happen without the corresponding IP.
