I recently dropped to the 3.25" upper pulley on the Whipple to add more boost for the track. I am not seeing any noticeable boost increase compared to the 3.375" pulley. I am still running the belt whipple sent with the kit that was for the 3.625" pulley. I am wondering if I am getting some belt slip and need to change belts. Do I need to change belts and if yes which one?

Thanks
