All depends on your motor set-up.

From my experience, the VP-U4 has performed the best. But you need to first determine your compression so you can get a good estimate of the octane level you need. The higher the compression the higher the octane. And you don't want to use too high of an octane as you'll loose performance as well.

So if you are in the 12/1 to 13/1 compression, U4
