lol thank you for the compliment, but this is my first balt, so im in uncharted boost territory's here with hptuners as well. Only past experience ive had with HPT has been on all NA cars. Previous boosted cars ran on other systems. If I find a limit on the E67 its going to be new to me so only time will tell. The only reason we ran rise rate regulators in the past higher then 1:1 ratios was for extra fueling, ive never ran into issues with back pressure on a fuel injector. Remember that the intake valve is open and air is flowing into the chamber when the injector is firing, so its not back pressuring the injector much at all, very different processes compared to the pressure that direct injection injectors are under.
That being said, for the setup your considering, I would run their BRFS kit for sure. It's a good investment, its going to give you the control of the fuel system your looking for with the E85, boost, and nitrous all in the mix. As far as what they are listing for this stuff....
"This kit lowers fuel pressure at idle to cure large injector idle issues and raises fuel pressure under boost to help fuel high HP applications."
Good injectors, like injector dynamics will have no problems running low pulse widths at idle even over 1000cc, that is why i stress the importance of a good quality injector over some of the **** ZZP sells, like the deka or lucas injectors (same goes for RC). The ID's will actually be good up over 100psi of fuel pressure, so long as the pump can support it, so you will have plenty of overhead as far as fueling goes.
I assume that the compensation for fuel at 17 and 12psi they are referring to is the ECU controlled fuel pressure rise?

Where ya located in michigan, maybe i can see if my buddy would be interested in giving you a hand tuning.

and that makes sense that it stops raising the fuel pressure at 17 and 12psi on the 2 models.
without the solenoid limiting the flow to the bypass, the boost will open the bypass 100%

Im going to go through a checklist of what I have packed up for the machine shop trip tomorrow. Driving about 3 hours to Indiana, so i would like to not forget anything and have to ship parts later.
Only having the bottom end honed, assembly balanced, and assembled. Am I forgetting anything? the flywheel and clutch are coming straight from spec and are balanced as an assembly.
-upper block
-girdle
-oil pan
-main bearings
-rod bearings
-crankshaft
-rods
-pistons/pins/clips/rings
-all the galley plugs
-outer girdle bolts
-old main girdle bolts for torquing/tolerance checking
-new main girdle bolts for final assembly
-stock headbolts for use with torque plate for honing
-main seals (will only need the one)
the just in case parts. maybe they want them for balancing but should be negligible:
-flywheel bolts
-both chain sprockets
-ati balancer (says not to alter/balance it)
thanks
If it fits, it ships

lucky, my machine shop refuses to assemble anything because too many clowns blow their **** up and then bring it back and say its his fault. I bring him the block with the bolts for the girdle and mains already installed, the crank separately, which is zero balanced independently of the rotating assembly and if the pistons and rods are new, those with the bearings for weight balancing of the rotating assembly. All the block ever gets is cleaned, honed and decked, and sometimes bored if its going oversized. I actually have to drop my other cylinder head off this week for cleaning.

I was talking to arm a week or two ago and didn't realize he was so close. So I asked his recommendation, and he suggested this shop. It's 3 hours from me, but they have done a few ecos and have a good relationship with arm, so it's worth the short drive.
