13.1 is pretty lean, so the powerwire helped me richen my air/fuel back down to a 12.8. This means that it was giving it more fuel with the powerwire installed. You would have to know your exact air/fuel ratio to determine if the powerwire was helping or hurting you.bigramman03 said:I don't understand what that means. Is that good or bad?
Yes and no. The small difference in power between a 13.1 and a 12.8 isnt going to be felt on the butt dyno. Without knowing your exact air/fuel, I doubt that you would feel the difference.bigramman03 said:If I know I'm running rich though, wouldn't it be worth a shot to take the Powerwire off and see if that helped?
