High rpm miss while in boost

I have a 94 z28 with a sts turbocharger. My car is having a slight miss in high rpm while in boost. You can feel the car pulling then letting off then pulling again. Not sure what the problem could be. I have a scanmaster and no codes came up - So I dont think it's a sensor. The opti, coil, all ignition is basically brand new. Does anyone know what the problem could be

Check the maf for oil, If it has oil on it that will cause the car to run funky. Are you running the STS pcv,and do you have a tune?

i had a high rpm miss one time on the dyno with my sts on my ls1.. turns out the plugs were fouled up, so try making sure you got fresh plugs, and the wires are connected really good
