...degree the cams. And with the gears set to zero or a stock set of gears, you should measure the JWT 400+ exhaust lobe center to be roughly 119° BTDC. If you adjust the gears when degreeing, you are setting the lobe center to whatever you want (within the adjustment range of the gears anyway); so if you measure yours to be 118° BTDC, you would need to advance by 1° to set them to JWT spec of 119°... or you could retard by 3° to set them to the OE spec of 115° BTDC. I'm not sure what all the tuners are doing with the exhausts to obtain their torque gains. Personally, I would degree the cams to ensure both banks are set up the equal and only tune the cam timing on a dyno. AND, I would tune the cams by adjusting both exhaust cams equally - not one cam at a time, and definitely not by different amounts.
