From what we have heard from the guys at PPEI their emissions compliant tunes or Street Performance Calibrations are actually reducing the number of regens and in turn aren’t using as much DEF.
They have installed an extremely high tech dyno and are continuing to monitor data to help back up their claims.
We are excited to see where this is headed as to be honest I personally was not expecting gains like this out of the gate!
