getting a bump in throttle response when hitting high beams?

[st577]

06 GT U7140 running 93 octane firm shift, I was heading home from Sebring last nite when I hit my high beams and felt a bump in the throttle I would turn them off and feel the bump again also with the turn signals, now why would a power draw affect the running of the car? I did this off and on for a mile or so, so I know I'm not crazy. I also keep getting a camshaft sensor code when running a tune on the predator. I went back to stock for now.

Thats a new one to me....does it not happen with the stock tune?

I drove with a friend today that has alot of knowledge he said that it could be the start of the voltage regulator going out but he was stumped also. We drove down the road set the cruise at about 45 then I hit the high beams and the engine stuttered I did this several times weird? As for the stock tune I guess it would do the same, I brought it back to stock but had a P060c Unknown come up and P2106 Throttle actuator so I went never had that before so I put it to 87 octane with 3.73 gears and now no codes for the day. Maybe the voltage regulator is about to give out?

It may be a poor ground or even poor connections at the battery. The Throttle actuators are very sensitive to voltage changes.

I'd listen to 4648 on this one, definitely sounds like a power issue..
