There is a 15 minute solution to the fueling problem that leaves the car perfectly stock no cutting lines splicing wires....... is $335 just too much money to spend for the easy fix??? anyway enjoy your projects
I'm done 
not sure but we are not stock once we get the tune and a pully, the sl55's ecu is set up to give the injectories the fuel they need at a certin psi(boost) makes it work stock,, now the crossfire has a tune and a pully so the psi (boost) is higher than stock (that means the psi (boost) pushes the fuel back ,, ( example ) put air in a flat tire no problem now put air into a truck tire that already has 100lbs in it ,, the air goes in slow ir at all the same with fuel the psi set by the ecu is good for stock just don;t add boost and you are fine, the sl55 pump by itself will not change a thing on our car. (correct me if i am wrong) filter/ reg. has to be changed also. a in line pump in front of the reg will change our psi, u would need another reg to decrease the psi of fuel. now that i am confused see what you can do. jim
