3g hemi gas mileage

Alrighty lets try to get some of the questions answered.

03' hemi 545rfe trans, stock computers (althougth I raised the shift points and firmness)
28 inch tall tires, 6.1 injectors, TTI headders with x-pipe exhaust, car intake manifold, 3.91 rear gears.

I switched the o2 to the passenger side per Chris at hotwireauto.

After much thought on the injector size, I might be to big with the 6.1 injectors so I'll switch them back to the factory 5.7 injectors as johnparts has eluded to.

The 03 hemis use only 1 o2 when using the aftermarket harness from hotwireauto, 04 and up use 2, again per Chris at hotwireauto, besides, I did try both and the engine ran like ****.

Gonna back flush the block tomorrow, so I'll switch the injectors at the same time.
