XU10J4RS head on XU7JP4 block

[maxzy]

I use to have the overfueling with RS injectors in XU10J4R in my 406 without ECU remapping ( My 406 have Inlet Manifold, A pair of GTI6 camshaft & Custom made 2.2" Exhaust system)

At the idle, Sometimes self-reving , Black Smoke and rough idle.

During Accel, Poor initial accel. the RPM will quick kick after 4K rpm (But I think std. XU10J4R was better)


So, I decided to take off the Green Injectors from RS and back to the stock XU10J4R instead, Until now they can run well without the problems not sure bout the HP and torque gain but I think it's a lot better than standard.
