8isGreat Posted July 10, 2021 (edited) 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? Edited July 10, 2021 by 8isGreat Quote Share this post Link to post Share on other sites
aztec Posted July 11, 2021 There is a thread or two on here with some experiences. Type tuner in the search bar. Quote Share this post Link to post Share on other sites
crusty Posted July 11, 2021 There is 19HP held up in the exhaust. No tuning needed to get it. Everything is the same as the 394HP Titan except the exhaust is smaller. Quote Share this post Link to post Share on other sites
8isGreat Posted July 17, 2021 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. Quote Share this post Link to post Share on other sites
