To carbon clean or not?
2017 GTI with 70k miles, tuned for 50k of those miles. I'm not having any symptoms to suspect there is a problem caused by excessive build up, but what's the general consensus on doing it at a mileage interval vs. waiting for a symptom of carbon build up (poor MPG, cold start misfires, etc) to appear?
I plan on keeping the car indefinitely so I'm not opposed to doing it if it makes sense to do so. I'd probably have the injectors replaced with the MK7 Golf R injectors (+15% added flow vs GTI) at the same time as my rail pressure can't keep up with the requested number.
