I went with 60s on my heads/cam package before planning on going to boost, but never could completely get the 60s working. On the decel I simply could not get it to command a low enough pulse width. The lowest I could get was 1.2msec pulse width. I need it to get damn near close to 0.8msec. One of the biggest problem is trying to figure out the injector offset table which I believe wouldve fixed the problem but no one has those values, and no one can seem to get them for me even if I gave them the injector and paid or them to test each value. I attempted to modify the offset table myself and still could not get it anywhere near where I needed. The decel was too rich and upon returning to the gas it would buck because it had too much fuel. I could not use the DFCO because it was already on and turning it to come on at too low just caused driveability issues. I talked to a few folks and came to the consensus that I need a vacuum referenced regulator to bring the fuel pressure down on the decels.
