  1. Headers Question S550

    The only thing that might need to change is the transport time for the O2s. sometimes they dont heat up fast enough with headers for the time set in the strategy so the delay needs to be set a little longer.
  2. Headers Question S550

    E85 might be the trick
  3. Headers Question S550

    It isnt easy running this new stuff. unless you are willing to revert back to the old days and hopefully not run a foul of the smog police, its difficult when it comes to modifying the exhaust system other than a cat back. The whole system is designed to protect the cats. I put the stock...
  4. Headers Question S550

    When I did headers and green cats on my 2013 Shelby GT500, I did nothing. It all worked. everything set within a few miles, no check engine lights. I tried to swap out the stock cats for the Gen 2 Green cats on the stock manifolds on my 2021. It was a bit louder and ran great. problem was it...
  5. Headers Question S550

    Maybe it depends on the year. my 2021, the fuel trims went crazy no matter which extenders I used. I could feel the engine getting sluggish. And the 02/heaters would not go complete. Engineer Mike had found ththe same.
  6. Mudflaps/rockguards… do they work?

    PPF and the low profile fender guards.
  7. Headers Question S550

    Keep an eye on your fuel trims. the defoulers throw the rear O2s off. The system uses them to re calibrate the fronts as they age. you might find the trims trending rich up to 10% or more. better off to get a tuners to shut the rears off. You emissions wont go ready. With the defoulers it...
  8. This looks expensive...control arm pulling out of k-member

    Looks like the nut broke of and the bolt beat the hell out of the cradle. looks like you need to weld a washer to it to relocate the bolt.
  9. Copying Sport Mode shift tables to Normal mode

    Actually its the coast down that has the issues. It seems sport mode is pretty much all 0 revs/second (-600 to 0) vs OSS. The way I understand it at whatever the speed change equals vs the drive shaft speed will initiate a downshift. Alot of the sport table has 0 OSS which I assume means a...
  10. Copying Sport Mode shift tables to Normal mode

    I just set th I just set the normal mode coast down table to oem. now its fine
  11. Copying Sport Mode shift tables to Normal mode

    Actually, I have sport, normal and track as well as LID set to Alt 0. Alt1 causes an intermittent flare 3-4 and sometime 4 -5. Ive modified pressure tables and inertia tables it shifts firm in all modes. using Alt2 in anything other than drag causes very harsh 1-2 shifts. it just seemed odd...
  12. Copying Sport Mode shift tables to Normal mode

    Has it always done that? does it change in different modes?
  13. Copying Sport Mode shift tables to Normal mode

    Weird stuff. I have been mucking around over the past while with the shift tables in Normal and Sport. I got it pretty good but I wanted to delay the upshift into 10th and down shift to 9th a little more. So I started playing around with the 9-10 shift area. And then I thought, why not just...
  14. 2020 Mustang GT Premium PP1 10r80 is rough

    Unfortunately I think the only way out is a tune. They pooped the bed with the stock strategy. I did mine with the help of a few here on the forum. Mine is a 21. It shifts fantastic in all modes. I made sport normal and track the same. They use the same characteristics (normal) and I tweaked...
  15. Active exhaust valve not fully open?

    Mine stay wide open when off. As soon ad you cycle the key they go to the normal mode position. I reprogrammed the settings in PCMtech so they are always wide open unless in quiet mode. As soon as I get it out of storage I'll down load the file and see what happens
  16. hood struts?

    Redline. Used them on my S197 GT, s197 Shelby and now this one
  17. Gear oil Torsen Diff

    Looking for a full synthetic without additive. All of the amsoil options have the additive. Red Line has two flavors, 75W90 and 140. Says the 75 is ultra light like ATF. Suggestions?
  18. A10r80 Tune

    You are an inspiration sir. Im in Ontario as well. I can tell you from experience that Wenegard was the most helpful for me. I have the tuning software and just wanted a flare problem removed that was happening in sport and track mode. He took over my computer and made the change so I could load...
  19. Possible impact of regulation roll backs?

    It wont matter. The next person in the high chair will probably reinstate everything that was squashed. I dont think anyone is going to risk this rolling back on them
