    You will find that in most cases of performing upgraded mods to bike the results fall short do to the inability to proper match all the upgrades. So it seems unfortunate that the tuner may not have been on top of his game to get all your bike has to offer.

    Plus please read the rules on language........:(

    Do you have a dyno sheet you can post? I'd be interested in seeing where the torque curve begins and if it's broad and flat or if there are any large dips in it. Also the AF ratio might tell a story as well.

    I do have the dyno sheet and I will try to up load it I am not to computer oriented but it start to flatten out right off the get go and again near the end of the run he thought maybe my power commander was bad so he tried a new one same thing so he disconnect the power commander it made more hp with out it but the engine ran badly said sounded to him like a timing confict with cams I don't no much about that stuff so I am kind lost

    Since the tuner was not the builder it's hard to lay blame without knowing how things went together. Are you still speaking to the engine builder? If so I would take the tune information to him and see what he will do for you. If he was the one who gave you the specs for the motor and what components to use he had to have some idea how it would perform. Start back with the builder and see what he thinks the problems are.

    It would be great if you get back with the forum so we all can see how the problem is resolved.

    1 tooth of on timing could make a huge change iMO, I would have the builder open up the cam chest and have a look
