I tried searching and looking through old posts but I can't remember for the life of me what the c7 stock pumps are good for power wise.

I just put a smaller pulley on my procharger to up the boost to 14psi and meth and I'm pretty sure I'm out of fuel. Rail pressure dipping down to 670-800psi and can't get the afrs richer then high 14s/15s

What are my options from this point?

stock cam car?

Yes only mods are procharger, arh lth catless and now aem meth + pulley

We typically see C7 rail pressure drop around 530whp on our mustang dyno, upgrading to Z06 HPFP and injectors will hold you to about 580-600whp. Then your low pressure side begins to drop. This is w/o using meth to compensate for fuel.

Without meth and the pulley it made 610whp/598tq and first pull with the pulley was 621whp/669tq

I ordered z06 injectors and hpfp today. Should I order the dual nozzle kit for the meth?

Yes, I would order the dual nozzle kit. No one ever likes getting back on the dyno and running out out of fuel!

With those z06 parts and dual meth, you should be able to go a lot higher hp. I'm at 808 with stock z06 fueling and procharger

I think you're about 75-100 hp off....
