I installed a Cobra Fi2000 Powrpak on my 04 efi road king. The tuner came preprogrammed but has three dials for adjustments. After install, I now have rough or, bouncing idle, won't stay running sometimes and the rear cylinder doesn't appear to be firing. The plugs, wires and coil are good. I have an after market air intake and exhaust pipes. The pipes are 4in VH and no baffles.

Can someone please help, or have dynamite for sale?

Thanks Dave

 

That cobra tuner has never gotten good reviews. Your pipes with no baffles will be quite difficult to tune with any tuner.

 

Well I read several reviews and all were very positive. Plus, I'm on a fixed income, disabled veteran, and can't afford $ 300+ dollars for a name. I was asking for help, not an opinion

 

I was stating a fact- not an opinion. Sorry that it's not what you want to hear. Call Cobra.
