Pulled MSD rev pill out  made it run alittle better still lacking rpms
Pulled plugs and they look little lean
Did compression test and have 155 psi in 7 cylinders and one at 145

Why lean?

He pulled the pill out, put it in the water and the cutting out/misfiring is gone. But hes now down about 600 RPM. He was spining in the 5100 range before and ow the engine jsut cant pull past 4500

Im thinking fuel delivery
