Do tunes have EBPV control?
I just ordered a phoenix chip today and I was wondering how the tunes would affect my Exhaust Back Pressure Valve. I assume the High Idle tune will keep it closed, but will the performance tunes keep it open at all times? The EBPV is a pain and makes me lose control in the ice and snow with the sudden acceleration burst when it opens and deceleration when it closes. If a constant fully open EBPV feature isn't part of the Daily Driver or Performance tunes, how much might it cost to have it put into the tune?
Thanks for any advice
