Honestly, I would leave the shift points alone unless you've done something to seriously shift the powerband up. On mine, it shifts from 1-2 at around 5450 and 2-3 at around 5650, which is just about pefect for this engine and gearing. BTW, the tach on the dash is not accurate - at least not on mine. It reads about 5250 for 1-2 and 5500 for 2-3, but the digital readout on the LiveWire shows the true engine speed.
As for the air/fuel ratio, I'm sure there is a correction to make for the MAC intake. Your choices are to leave it alone, get a tune from a James, or put it on a dyno and monitor it with a wideband and make adjustments based on that - but it would still be better to send him the dyno results with A/F and get a whole new tune than it would be to adjust the entire curve up or down from the device. .
Limited02, my wheel and tire combo is definitely heavier than what you're running now. It's 65lbs vs. 56lbs for my stock wheel and tire. The 17" rims are only 22lbs like my stockers, but the tires are 43lbs. Toyo listed them as 39lbs on their web site, but they actually weigh 43lbs. I was annoyed about that because at 39lbs they would have been the lightest tire available in that size, and that's why I picked them.
