Do both in parallel and I'd guess the performance gained from regearing would be a more significant improvement.
You're looking at a smaller change so it might be closer than trying to add power to make up for a significant tire size upgrade.
I'm looking for as big a power increase as I can get for the buck, and specifically in torque.
Not to beat up the topic, but it is an interesting discussion.... Regearing would not give me any more power. I can use 4th gear to get the RPM up to a higher torque number.
Spending the money for a gear change, would not be my first choice. I'd rather spend $112 for the cam, and $600 for a header, 2.25" exhaust tubing, a free flow cat, and a turbo muffler. THEN, I'd have the increased power I want and would not need to change my gear ratio.
Gnarls.
