Sounds lean. set you're needles back to stock settings and lower the idle then re-tune.

When you see blue smoke at WOT with consistent temps and no lean sputtering you have a good tune then.

What are your temps?
it sounds like you might have an air leak.....
seal your engine, replace your fuel line, and check your fuel tank....

check youtube.com for instructions on sealing an engine (if your not sure how to)
