SignUp Now!That is why I was saying larger injectors. At least 750's. Then just the file. At static fuel pressure, the 255 can handle 750ish whp. So then the next issue is obviously the 668's. Those are running short at static fuel pressure. So the two easiest options are add a vacuum hose to the fuel pressure regulator, to increase the pressure on the 668's and get more fuel. The X-1 can handle that.
The next is buy larger injectors and adjust the tune for the injector size. Since injectors are easily available compared to the mystical 7th, that is a easy choice.
I would opt for thrying the vacuum hose to the FPR first.
I have some 850 injectors I am going to try some day or maybe just buy a Mustang and grow a mullet.

Which charge pipe ?
Look over this link. http://www.rceng.com/technical.aspx
Your effective injector size, at 8 psi of boost, with a boost line going to the FPR, would be a 726ccm (ish) plenty more fuel.
Just "T" off of where your boost gauge vacuum hose is. That will be a good spot.
Also, another point to add, is the another X-1 owner is running 850 or 880 ccm injectors. I know that APR has the calibration file for that size injector, since it is on their turbo project truck. You could always call them.
Never mind.
