408 tuning with a Wideband sensor

On the ride home tonight when it was cooler outside, the 40-60mph went back to high 13's low 14's. I think I'll leave it there so it doesn't get too lean on chilly San Diego nights. I did notice it gets a little lean under light acceleration and then goes to mid 12's once the PV opens. A more aggressive pump cam should fix this right? It's currently the stock pink one on the #2 setting. I could move it to #1 which should help some I think. I may order a a blue cam to try as well. Is it recommended to change the cam on the secondarys to the same one?
