No need for a Power Commander with my Muzzy header with custom Magnaflow/Yoshimura silencer, Pipercross air filter, etc... It'll still be progressively too rich from mid to high rpm. stock or not. Rotating the main throttle sensor counterclockwise just a tad adds more fuel at low rpm where it's needed most, especially near 2800 rpm.
Also, sealing off the PAIR valve reduces backfiring tendency upon engine braking.
