I find the spot where he talks of the underhood air intake temperature being far too hot. 175° F !!
How can so many fail to understand this and add these "cold air intake" kits that do just the opposite of what the name implies?
I also wonder where he moved his connection for throttle position to after the PCM didn't like the voltage offset introduced by tapping into presumable one of the position sensors. Or did he do some sort of workaround for that.
He's probably gone in with a tuner to massage the stock PCM and also using an aftermarket PCM to control the VW ignition coils so there's gotta be some sort of connection between the two. Not sure which one controls the injectors.
