[vwfox361]

At 44psimy car was leaning out after about 4500 to redline bumped up the pressure to 55psi got a little better but still leans from 6000-7200. should i increase psi or would it hurt my motor?

it is probably the tune that is causing the lean condition. get that sucker dyno tuned if you want the most out of it.

Its the tune not your fuel psi. its whatever they set your fuel table @, when you raise the fuel psi your increasing the amount of fuel that is being pushed through the injectors @ the same preset (tuned) injector fuel table rate.

should i remove the chip?or get a fuel controller and wideband?

Fuel controller and wideband would work- proper tune on a dyno and the street with a wideband and a true tuning solution that's not a piggyback would be MUCH better. If you're already going to spend the cash on a wideband, go ahead and look into one of the free chipping solutions for OBD1 ECUs.
