I have
Stage 1
H Beam rods

I would not recommend over 8 pounds max with pump fuel . . .

You would have to get your tune checked but with water injection 10 should be ok
may pay to put a pressure switch on the water line and a light so if your running hi boost and have a prob with the water you know immediately , there is not much margin for error ..

With water injection and your tune being correct you can go to 12 psi on 91 octane,

I overlooked the water injection in his list . . .:stoopid:

put some 93 in it and go to 15 psi . . .

I run up to 12 lbs with water injection and the same mods you have on your bike. But I am usually only in the high boost for a few seconds at a time. All we have here is 91 octane. So far so good. But I am usually just on 7lbs, the 12 lbs is when I feel like getting silly.
