Guys cant figure out what the hick up / slight bog is. I was thinking may be its mis-fire but i dont see my EGT Temp spiking. Just checked my MPG & only got 13.1per gallon but i think this is normal? Before my 3.00 pulley & new plugs i was getting high 14 & 15mpg.
Well its so easy to get power now so im thinking the pulley is not helping me out on the MPG.
So what can be the cause of this hick up?

O.K. Checked the color of the plugs & its getting to the Tan color / Gray color.
But...yes but. Some plugs are at the tan stage still & while other have already hit the gray side.
Oh with the THUD part of it. I just tried changing the gap. From .037" to a .040". Still a slight THUD but not a long duration of a thud. So not a hick up / bog feeling.
Although i can still hear the THUD just a tab bit in the higher RPM range but still driving very slowly.
Maybe my car just doesnt like the smaller gap size?
