Thanks for the advice 8isgreat. Will the same exhaust for the Titan fit the van?
Side note, I contacted Bull Dog Performance and they said they do not have the software for the 2021 Nissans to use their tuner.
I recently replaced our 2016 NV3500 with a 2021 4x4 NV3500 conversion from Tim Dahle Nissan. We are pulling a travel trailer which weighs around 7,000 lbs. Is there anyone that has tried tuning or chipping the engine to get more performance while towing?
