Fuel pump rewire kit help with fuel cut?

[91tsi2wd]

I just purchased the fuel pump rewire kit, and I was wondering (kinda dumb question) will this help at all with raising the fuel cut on stock fuel trim? just curious...thanks

Since fuel cut is based on airflow, upgrading the fuel system (or rewiring the pump) will do nothing to raise it. The ecu still sees the same amount of airflow, and will still cut fuel at a certain airflow.

Hes right. Fuel cut has nothing to do with the amount of fuel being flowed.

Its called fuel cut because the ECU cuts of fuel to the motor when it sees to much air being fowed

All the rewire will help with is leaning out on the stock fuel system at 15psi.

Don't bump your threads.

, I fixed a major boost leak today and wow, I gained 3psi and dont have no more boost spikes. Very surprising what it can do to you motor when you have boost leaks. Still cant lean it out though.

I told you so! Did you finish the leak test? Did it at least lowered the IDC?
