      So? Did you find a smaller jet than the 50 shot?
      Find any time/energy to work on installation? Atco raceway appears to be open. lol

      Life got real messed up again for me and took up all my time.
      This Saturday was the first time I had a chance to get out to the garage.
      Also this Saturday was the first warm weather we have had, and it went from a cold 40 to a hot 80 degrees F.
      I had the truck on wheel dollies and moved all the way over so I could get one of my other trucks into the garage when it snowed, that way I only had to clear the snow off one vehicle each time the snow fell.

      Got the truck moved over and reinstalled my EGR system and now I have to get all the monitors to run. There may be some tuning required.
      At least I don't have to put smaller injectors in this year, should be able to get it ready in a short amount of time.
      Once I get a good sticker on it, I plan to try to test out a different EGR system that I can leave on all year.
      I currently have a DPFE egr system. I want to test out swapping to an ESM egr system.
      If this works I can make my own egr tube with the tubing bender and flare tool I used for my 2004.

      After this experiment its back to trying to find out where to mount everything for the Nitrous kit.
      If this goes like last year it may not be until September before I am racing again.
      Here's hoping this year goes better.

      I hope you get some time to work on the good stuff(fun stuff). This weather has been extra weird this year. We've been dry and near 75 for several days, rain yesterday and under 40 all day today. Tonight we see freezing again, and maybe 60 and sun tomorrow. This is fun?

      The benefit according to Ford is that the restriction orifice was moved from the middle of the egr tube to the gasket.
      The ESM system egr gasket is actually the restriction orifice now. The DPFE sensor on the DPFE system measured difference in pressure across the orifice in the egr tube and the DPFE sensor in the ESM system measures the difference in vacuum across the orifice between the egr valve and the intake manifold.
      The real benefit is that when the EGR valve is closed there is no pressure or hot gasses pushing against the DPFE sensor so it lasts longer.

      One benefit for you might be not blowing the DPFE hoses off at wot due to high back pressures from having a turbo. The EGR is closed at wot and the ESM egr valve isolates the sensor from the exhaust when closed.

      The benefit for me would be that I can make an egr tube from stock 5/8 stainless tube and bend it any way I need to for fitment.
      I would not be able to do that if I needed to have the two little tubes for the DPFE system's DPFE sensor. I would have to have some welding done and I would rather be able to do it all myself but I don't weld.

      Maybe you could teach us as you find time to move forward with this. I'm always interested in updating technology on my 19 year old vehicle. lol.

      Ditto, I would be more inclined to keep the EGR if it was less trouble to fabricate the EGR pipe, and to have the DPFE last longer would also help. I'd try to keep it since I think it is somewhat beneficial, much more than the cats. I could adapt it easier with my old 92 Lincoln also, I've been planning to delete it since I'd have to have a custom length EGR pipe, and add the bung to a header.
