    Great video. After watching it, I was thinking about how it would be nice to have the right/perfect allen wrench for the job and stumbled across your Pelican thread. Fortunately it looks like there are now 4" models available, although I'll likely have to remove half of the top "loop" as you did. Thanks again for the great videos.

    Hey i have this setup and the previous owner took out the 02 sensor and that’s what I have. Have had it for 10 years runs well but now the plugs are white looking like running lean.

      Sounds like it's running open loop then.

      Yes I think that is what they guy said when I bought it 10 years ago. How do I deal with tuning when its like this and or what is going on with that type of running. I am used to carburetors and learning all i can with this injection, thanks!.@@JoeEngineer

    Will having an incorrect duty cycle, calls the engine to tub slightly under acceleration with a frequency that’s around 0.5hz?

      Very possible. The main difference between closed loop and open loop performance (besides emissions improvements) is slightly more refined stop and go behavior around town.

      Ok that could be it. It is a little touchy around town for sure. Also has a little jump (almost like turbo lag) around 2500 rpm
