Fred I have read all your tuning threads and love them. I know small holes create more pack. Should I try 4 x 1.1 Front and 4 x 1.2 rear. Was going to order taper or drill out some of the blanks. Recommendations would be greatly appreciated. Thank you.
Use the same ratio but smaller and more holes. If you are using 2x1.7 approx 4.5 ratio, then 3x1.4 or 4x1.2
