My PVC will be in the mail tomorrow, I only saw 2 tunes on Dynojet's webpage. Is there anyplace to start with tuning this thing?? Just new to the power commander .. thanks
Is the auto tune plug and play or is welding needed for the 390?
I still have the factory headed pipe with factory O2 sensor
............. I was just pointing out that there's much debate as to the value provided by the AutoTune. The delay from the sensor being that it is tuning for what your engine had previously been doing, not what it's doing now, having been one of the major points of contention. I'm not familiar enough with it to have an educated opinion on the subject... .
