How old is the engine? I found it took a while for my p5 to want to drop to a smooth idle right after a wot pass. If it still has pinch left you won't be able to tune out that two stage idle.
What is glycol? Thanks for the suggestion Ill have to try that along with my new tank when it comes in. Engine has almost 4 gallons on it so its nice and broke in now. It still has pop and resistance when turning it over cold with no pinch. It doesnt have a 2 stage idol. If I lean out anymore the LSN and/or raise the idle any more then it will come in high for a bit then drop down. But my tune is set just before having a 2 stage idol like I mentioned in the first post. The problem is the weak and consistently decreasing idol tendency only after high speed passes but not moderate or low speed passes. After letting off throttle it drops immediately which is good but keeps dropping then dies. Since its after high speed throttle I guess the answer is right smack in the middle of my face huh? its got to be the HSN but usually its never that easy or maybe it is for experienced tuners. Im definitely gettin there
