Problems with my s14 when turning

My 240sx Stutters and putters when making Right hand turn which is weird and Ive never understood it. It will get to the point where it will dog down and I cannot rev it past 3500RPM’s but if I hold the gas at WOT it will eventually work its way through. Anyone have some insight to what this is?

Fuel pressure, plugs, wires are all good, I always run '93 and use injector cleaner 2x a month. When this happens I also get a smell of richness too.
