Application Notes:
We’ve found boost control on this application to vary wildly from vehicle to vehicle, even on the factory tune. Some users in cold weather and cold intake/coolant/oil temperatures together may experience a momentary “cut” if logged actual boost pressure exceeds the ECU’s target.  We have retained the overboost protection feature for safety.  This will feel like a very short substantial reduction in power, usually followed by an upshift to the next gear. If this occurs we recommend trying a tune with midrange dampening.

No additional tuning can be changed at this time.
