  1. OEM exhaust header nut torque

    Turns out these things are lock nuts. Manual says initial torque 17 lb.ft then 24 lb.ft. is that plus the torque it takes to turn the nut or less the torque it takes or is it including?
  2. OEM exhaust shorty "headers" material

    Anyone know what material and guage the stock oem headers are made of? I suspect 409 since it rusts. Going to weld a 3/8 flange onto the drivers side. Just getting the fill wire and welder settings sorted out.
  3. Gforce cat replacement

    Well The swap over from stock oem cats to g force epa approved cats had begun. Bought the cat delete pipes from 2m Fabricators and tig welded the cats in. Phase 2 us where it gets tricky. Welding the flange onto the header. I think in order to do the job right, it has to come off.
  4. Pcmtech - changing tcc lock up

    Further to my Ratiotek question. With this kit, it gives you the option to firm up the converter lock up. They recommend changing the lock up so it's at 5th gear. I looked this up on PCMTek. There is a lock up section divided into every drive mode Ford has. I believe the ones I'm interested...
  5. Anyone familiar with the workings of the 10R80 valve body?

    Why I ask. I'm thinking of doing the RatioTek reprogramming kit. There are two holes they want you to drill into the lower half of the valve body, which appears to be at the A and E solenoid channels. Any enlighten me as to what these holes do (pressure reduction. Speeds up fluid dumping?)...
  6. Rear O2 sensors-longer leads

    Is there a rear O2 sensor that works on a 2021 GT that has longer leads?
  7. PCMtec Shift characteristics-Which one is Track Mode?

    So I understand Base is normal. Sport is sport. Drag is apparently Sand. There is a snow mode so I assume snow is snow. I'm also assuming mud is Track. There is definitely a difference when switching from 0, to Alt1 to Alt 2. What makes me wonder is that in Track mode, it wont downshift to...
  8. Derale 25792 external thermostat-Remove Thermal bypass

    Anyone use one of these? If so, would you remove the thermal bypass entirely or use the one that allows full time flow?
  9. Normal mode skip shift elimination-PCMtec

    If one wanted to eliminate the skip shift in normal mode on the 10R80 with PCMtec, would it be as simple as setting the rpm to 10000 on each skip shift column in table AuF67261? Asking for a friend.
  10. Gen 3 2021 PCMtec Fan threshold change for 170 T stat

    Is it just the one table (ECT)? I figured 40% fan speed at 185 degrees and leave the rest as is? Anything else need changing?
  11. Wenegerd or DRP to replace roush tune and trans strategy

    I have a 21 Mustang GT with a Roush stage 2 supercharger. The trans shifts great...in normal mode. In sport, sport plus, etc. It intermittently was flaring 4th to 5th. after a revision, it seemed to go away, and then 3 to 4 started doing it and 4 to 5 was crisp. now they are both doing it...
  12. Ratio Tek shift kit for the 10R80...anyone try it?

    Anyone install one of these? What's your opinion? Worth the trouble?
  13. Mak Performance

    Anyone know if Mak performance is still in business? Several attempts to contact them with questions have gone unanswered.
  14. Cat converter option

    So after reading many posts regarding cat failures on boosted cars, I started to lookalike alternatives and the operating characteristics on the Gen3 coyotes. We don't have emissions validation inspections in Ontario Canada, but you have to run cats or it's a hefty fine, possible plate...
  15. Suncoast valve bodies

    Any one use one? What's your thoughts? Any one have a tune like a Roush tune for their SC? Can they program the solenoids into the TCM without disturbing the aftermarket tune?
  16. 2021 Roush IC circuit operation.

    The because I have to know file. So driving around yesterday I noticed by IAT2 around 118-124 degrees. As soon as I stop at a light it jumps to 140. Ait temps around 80 degrees. Start moving it drops back down. When I got home I let it sit in the garage it get up to 159.. I turned the fan on...
  17. Roush tune update

    For those that have done this themselves, is the crank position sensor relearn necessary when updating the Roush tune?
  18. Magnaride rear shock removal

    Any one ever have success removing the rear shocks from the lower control arms? I got them out when the cadle was out. Doing it in the car is a different story. I just can move them around enough to get them out. It's like a evil genius designed the opening.
  19. 2021 Mustang GT Auto with QA1 Rev series cabron fiber driveshaft-vibration

    Any suggestions for reducing the vibration at 60-80mph? I expected some but I have no idea what is the expected level should be. It feels like I'm on a rough road once I hit 65MPH through 80MPH. I can feel it a bit in the seat and in the steering wheel. I contacted QA1 and they say I should...
