Evo X upgrades

[Speedfreak]

The 044 is a tried and true pump. It supports an easy 600whp, and people have pushed 700+whp with a very efficient setup. I personally have supported 584whp on an nsx tuned by Shane(backed up in Chicago with 560whp on a stingy Mustang dyno in Chicago). If it's the pump, you have a lemon, otherwise it shouldn't be your issue.

Edit: I'd be willing to lend my brain to help you diagnose the issue if you want to stop by some time. I just can't watch this fuel system situation any longer.
