Code P0340 after cam install help

[Garrett brittain]

I have a 200 amp alternator, plus an Aeroforce Interceptor gauge that displays the voltage going to the battery in digital format. It never has a problem charging at low RPM’s and I have a lot of added electrical components.
Told ya Lito was the way to go.

Alright, I’ll either go with the SR performance 200a or a Denso 165a. Both have good reviews at a similar price, guess it just depends which one will ship quicker lol
