x2. Don't touch the pulley until you max out timing on the stock pulley and prove that you can run KR free on that. Scan in many different conditions, don't just run one scan and think you are safe. If you run KR free with max timing, it would be safer to first drop to a 3.4 and scan again. If you get KR under certain conditions, then you can drop timing to keep it safe.

If you go right to a 3.2, you will have to drop a bunch of timing, and you will have no power.
