how much power loss????
#11
It wont work mainly because the shims arnt the right size, second the lb7 dosen have the safe guard programed in the pcm to where when the psi reaches the high then drops it limps, the lb7 dosent trip a limp mode code so unless you dont want your rail psi to drop to 22000 psi then you dont have to modify it, danny modified his he can tell you the size and how to do it.

I just went thru all the power loss stuff and with 2500HD HELP WE FOUND THAT MY CP3 was bad. Do your self a favor and test the pump pressure while driven. Actual pressure should match the desired +\- around 200psi or so. You can read my long thread on the injector regulator and that will give you a good idea of what all it could be and how to check each thing. Good luck but I bet the cp3 is going...
