First time Holley tuning help

You need to know your vacuum at idle in gear (if auto) and what rating power valve you have installed. What list # Holley? How much of the transfer slots are exposed? Are you running a PCV? Jets are not an issue at this point. You will likely need to adjust the secondary stop screw to add idle air bypass so you can back off the primary idle stop screw to close up the transfer slots. This is common with bigger cams. You need a power valve rated at close to 2" below what idle vacuum is in gear usually a 4.5 will accomplish this.
