Any idea why the 2nd position isn't working?
But I'm not seeing an increase in fuel mileage on position 2The changes in power between the switch settings (off, timing, timing + fuel) are so small that it's hard to detect. I think my switch may be busted though, I don't even see a difference in egt temps between settings anymore.
What surging problem lol I don't want the 3k if it's going to surgeGo pedal feels better, but I have that damn surging problem back, so I'm switching back to the 2000 tune.
I gotta say that it's pretty cool you had first hand experience with the (suspeceted?) owner of quadzilla. Being new to the second gens I kinda feel like I missed a lot of the "good ol days" and that there starting to slowly fall of the map. Thanks for the info, currently I'm outta town and not with my truck. When I get back ill import all the data off it and see what I've got and if I want to "upgrade". Again thanks for the info!I was a beta tester for the XZT back in '07. The '01's and '02's had experienced surging issues on #3. Not all of them. Like Trax said, all trucks react a little differently to the XZT, but the ones that did were pretty bad. I lost track of how many beta tunes Quad sent me to try out. It got to the point that he requested one of us visit his shop so he could see the data live. None of us (that I know of) were from TX, so I don't know if he ever found a donor truck. I ended up going through a divorce and dropped off the radar for a while. When I came back, Quad had just closed down. A little research showed that he ended up remapping the whole fuel curve to fix the surging issue. I wasn't able to ask him directly, but some members suggested the new tunes in the sticky are all post-surge problem tunes. I tried the 1000 and they were right, no more surge. Then I tried the 2000 cuz I wanted something more aggressive. With the 2000, I could barely feel it. Enough to not be bothered by it. The 3000 is supposed to be the most aggressive, so I tried it and the surging is definitely there. Not as bad as the beta tunes, but it's there. I guess my truck just doesn't like it. The 2000 is good enough for me. Like I said, I only use it when I tow.
