Hi, I have the bullydog GT gas tuner installed on my 2013 NV3500 passenger w/ 5.6 V8. I installed the premium fuel tune, w/ wide open throttle restricted removed, and 2 degree spark advance. I don't know how it affected fuel economy, but it sure changed the character of the engine and transmission. The engine was quick before the tune, but now it really rips. For a truck that weighs 7000 lbs, it really moves out from a dead stop. With traction control off, it will easily spin the rear tire from a dead stop if you boot the throttle. The truck is even more fun to drive now with the tune. As an added benefit of the tune, the transmission shift points are greatly improved. Before the tune, I always felt that the transmission upshifts were kinda' delayed, especially when climbing a hill. Now the upshifts are very crisp and much better timed for the power ouput of the engine. I haven't tested the fuel consumption on a trip w/ the tune, so no data to report. Pete Fazio

HI All, I have a 2013 NV3500 Passenger and I am interested in getting a Quigley conversion. I have been to the Quigley factory, gotten a tour and talked at length to the Nissan sales rep. I live 30 minutes from Quigley. When I was there, we discussed the addition of diff lockers to the axles. For the rear, as of Dec 2014, Quigley was unaware of any locker for the rear diff. When I asked about getting an e-locker or air locker for the 9.25 AAM front diff, the rep was pretty hesitant about installing one in the front steer axle. I got the feeling that they did not really want to consider a locker for the front diff. I am still "up in the air" about deciding on doing the conversion due to lack of front or rear lockers and the single speed transfer case. Now, it's mentioned here that the transfer case that Quigley puts in the NV is really a 2 speed box but with the Lo-range blocked out by a bracket. The Nissan rep never mentioned this to me during any of our conversations. If this is really the case, and the bracket could be removed after the "official" conversion, then the NV would have the ability to have Lo-range, but with the possibility of going into limp mode due to a fault code. Can any of the Quigley converted NV owners confirm that this is really the case? If so, does anybody know what the Lo-range ratio is ? This may push me over the edge to get the conversion done this summer if I could have a 2 speed case and a front diff e-locker. Pete Fazio
