While doing my 2Bar SD tuning I noticed my Voltage starts out at 14V cold then down to ~12.8 when hot. Seems like I need an Alternator but thought I'd see if anyone else had input since I'll have to pull the procharger. Also, I'm seeing 0.3V higher with a meter at the Alternator so I'm going to replace the battery cables.

If it's charging it will stay 14 volts or more. Belt could be slipping when hot. That effects your air/fuel tuning also.

Thanks, 14V was what I thought. It's not slip (new belt and voltage doesn't vary with rpm) so it must be the Alt.
