Default Timing?

I just put in a set of andrews 48H cams in my 2009 FLHTC. This is the first time I did this Mod myself. After I got everything together, stated it and took it out for a test. At 3000 RPM it started to breakup real bad. So I reset the Push Rods again making sure I followed the proper procedure. It still breaks up at 3000 RPM. Could I be one tooth of on my timing? Anyone?

Yup.

The Cobra Power unit will only tune for fuel right? No timing or am I thinking of a different Cobra unit.

Yes the cobra pro tuner only changes fuel mixtures. So I need to get it dynoed?

Yes, the dyno operator will put a sniffer in your pipe and check your air fuel ratio. Im thinking this will show you were your problem is, likely real lean were you are "breaking up"?
