"Does not run past third throttle" means it does what?

You just replaced the filter .... did nothing else? If so replace the stock needle with the DJ needle and put the clip on the 4th slot from the blunt end (top). Change nothing else.

If you are saying you added a speedstar air box (the open one with the K&N filter), you will definitely have to do some jetting work to get it back to running correctly. BB

If it was me I would put the stock air box back on and leave the stock jetting in until you get a more open exhaust on. My op anywho.

I'm with Musky, don't just do an airbox change... open up that exhaust!

Then rejet!
