I got a check engine light last time I put my stock intake back on because I forgot to tighten one clamp (was in a rush). There was no traction control light. As soon as I tightened the clamp and turned the car off/on, it went away. So I don't think this is true.

Unfortunately, this is relatively impossible. CEL's happen when the ECU reads certain values from sensors. Typically, this is either an "out of bounds" value (a sensor is reporting a voltage that's not within expected spec in the ECU; e.g. cam advance problem) or a predetermined condition from multiple sensors that calculates out of spec to the ECU (One sensor reports one condition that conflicts with another sensor, both are within spec separately; e.g. My CEL. Engine was receiving a lot more air than the MAFS was reporting).
So it's highly unlikely that John's tune caused a CEL. He doesn't touch how the engine receives CELs. And I'm willing to bet the ECUTek tuning software won't allow him to run a part over spec; such as cam advancement. The only exception I can think of is RPM, of course. He can tell the ECU to let the motor rev past what it can handle, but even then. The CEL would be caused by the mechanical damage as a result.
I'm willing to bet he knows what he's doing and it sounds like there was a problem with your evap system.
