Bonneville America Forums Forums Technical Forums Performance Mods What would you suggest?

I have my jetting dialed in according to Dinqua's calculator, but since wrapping my headers I'm getting a lean pop when I come off the throttle at freeway speeds. Since I'm mostly on the needle at that point would you suggest upping the needle by one shim? or do you think I should up my mains by a couple of points. Thanks in advance for any advice.
