RE: Engine tuning
adrenaljunky, did you break in your engine first??? You can not run it peak without first breaking the engine in. when an engine is new, you need to run the engine for a bit to make all the parts wear into each other. if this is not done correctly, you can wear them too much and drastically shorten your engine life. read your manual, it will give you the best way recommended for break in the engine.
