I have a 2012 road glide ultra with stage one upgrades Thunder Max tuner, Vance&Hines true duals, and K&N ire filter. Recently replaced rectifier/regulator because of voltage issues and bike will run great. My issue is I'm getting 3 codes and bike goes into limp mode. I reset the , run great for a day then got P1511,P2101 and P2176 I'll reset runs great for a day then throw them again. Cleaned pins and greased connections on both ECM and throttle body, same issue . Any thoughts anyone?
Are you referring to the motor and gear set on the left side of the throttle body looking at it from the air cleaner side. The only other connection behind the air cleaner are the injectors This connection

check those wires and pins inside that plug. Looks like it's been stretched and under some tension so the possibility of pin backing out or coming disconnected from the wire is possible. Theres an extension kit available usually can be found on ebay.
I'm by no means a throttle by wire guy but I do know a little about closed loop servos.. The errors you are getting appear to indicate that the throttle servo is not operating correctly. The first is simply going into power management mode due to the other 2 errors. The ECU seems to be having problems closing the loop at idle.
You say you had regulator problems.. I suspect that it was due to the battery voltage going too high. Chances are that the might have burned / stressed part of the electronics. You probably already figured that out.. OK, So which part? The ECM or the Servo in the throttle body. I would guess that since you are stage 1, you could try the stock ECU and see if the error returns. If it does, it's likely the throttle body. If it don't it's the driver in the Tmax.
Since you didn't get a "P2135 TPS Correlation Error" I'd suspect the Tmax driver but you might get away with a clean and lube of the guts inside the throttle body control.
As usual, if you blow anything up, I disavow everything I've wrote here..
