Bigger injectors are not the issue, its the boost holding the fuel back in the pintel of the injector. I have written about this time and time agn. The rail pressure has to keep up with the boost pressure, I cross connected my stock pump with the boost from the manifold and got crazy rich at 20 psig boost, ran into 9's until I tailored the boost signal to contol the fuel pressure when I got into the upper boost ranges. Currently running a 185 pulley with many mods to the head/manifold to promote deep breathing, and of course the dual cai the I pioneered for Rob. Not lean any more.Woody

Iam impressed with the 23psig readings, where is that measured ?
