Aftermarket fuel pump with stock ecu?
Would a Walbro pump anymore fuel with a stock ecu? Or would I have to buy a upgraded ecu to add fuel? I have been running a midpipe on non-seq turbos and it boost creeps to 11-12 psi near redline so Im gonna need some more fuel. Thanks

No, you're going to need a new ecu....

An "upgraded" fuel pump won't add more fuel to your setup, which isn't the problem anyway.

A fuel pump doesn't add more fuel all on it's own. The fuel pressure regulator is what regulates the pressure regardless of how big the fuel pump is (unless the FPR gets overworked).
