Rossoh, you should tune your LSN after the HSN is set, let the engine sit on the box and rev it up high make sure that it clears out all the fuel, then hit full brake and count to 6, on the box lean out the LSN until there is a hesitation on the box after a 6 second count. If your engine is still under a 1-1.5 gallons, just leave it a little on the rich side and just be easy on it till it breaks in all the way.
