  1. Coolest thing I have seen in a while. Every shop needs at least one! https://www.instagram.com/p/CCI7Yx-jfer/?utm_source=ig_web_copy_link
  2. It took hours any many revisions to fix the driveline clunk issue I experienced. It is a combination of upshift and downshift scheduling problems, torque converter lock up and unlock at the wrong times, desired output torque factor issues, torque adder issues, stall torque management, tip-in torque management, limit torque management, torque reduction, and more. Basically the stock tune is commanding too much of everything at the wrong times. Mine shifts like butter at part throttle and is nice and crisp at WOT. The way it should of been from the factory.
  3. No. I am having a "tight converter" condition, not a cam retard issue. My tune has 7 degrees of cam retard that starts at 3800 RPM. (2 to 7 from 3800 to 6300). It has been spot on in all the logs.
  4. Any tuning issues with yours? Especially when coming to a stop? (Driveline clang).
  5. This was final results. 28 degrees of timing and wouldn't make more at 30. On E85. It's all she's got.
  6. Man there were a bunch of issues. Transmission shifting all wrong from harsh engagement, long shift times, shifting st wrong RPM/MPH, the list goes on and on... With engine the idle was set to high, it would die at stop signs, it ran rough at a idle and would vibrate the whole truck, it would surge at cruising speeds, herky jerky taking off, and much more. All frustrating and expensive.
  7. Update: First tuner couldn't refine all my quirky issues. I then purchased a HP Tuner MPVI and starting working with a remote tuner, that didn't go well. So at my 3rd tuner now and truck is being tuned by #3. I have spent way too much on tuning and not real happy with some folks. These newer trucks are a completely different animal and a bunch different than the LS stuff. I will update once I get it back hopefully this week from #3. Here is link to my current tuners site. He has one of the baddest dyno's in the country! https://dbrhighperformance.com/services/dyno-tuning/
  8. If anyone is trading in their jalopy for a new 19 and have a Corsa catback you want to sell hit me up. Thanks
  9. Definitely one of the best things I did on my truck!
  10. Dyno - 409 HP and 426 TQ on 93 octane and Mustang Dyno. Torque reading looks all over the place. He got 1-4 shifts spot on. Not happy about my clunk in drive-line, more noticeable now with bigger cam. Believe it will go back to tuner for some more refinement.
  11. Correct add sensor in fuel line and connect it with truck harness. The harness connector is on drivers side frame rail by transmission cross member.
  12. Thanks I was aware of how to turn traction control and StabiliTrack off. Video was me just playing around. I understand the concern on the driveshaft too. Thing to note is a crew cab 2WD truck has a considerably longer driveshaft than the crew cab 4WD truck like mine. I am planning on a two piece conversion in the near future. Thanks
