  1. Traction control S197 vs newer

    I can do the same with my gen2 pp. Oddly track mode shuts things down sooner when hanging the rear out a bit. Can push through it though if not careful.. especially if people are on the side walk near by.
  2. 2021 GT500 headers & cats on a 2021 GT 5.0 w Roush blower, will they fit?!?!? UPGRADE....

    It's usually the cost if gt500 setup can be had cheap enough. Mainly for the cats. Oe wins here for longevity typically.
  3. 2021 GT500 headers & cats on a 2021 GT 5.0 w Roush blower, will they fit?!?!? UPGRADE....

    Interested to know. Looks like pass side cat might bolt to stock header. Driver side looks like a flange needs to be welded to header or re orient flange on gt500 cat and use gen1 header. The firing order is different and the primaries come together differently than the yote. Believe it matches...
  4. MAK performance or 2M Fabrication??

    Haven't had issues. Fit great. The provided clamps are wrong size but I wanted to use different anyways. I added flex joints to each side too. Shipped out few days before their self proclaimed deadline that was listed. At least they are up front about being dicks. Many other places will happily...
  5. Tremec vs Ben calimer

    Great first hand experience thank you for sharing. How's the normal shift quality compared between the two? Gear clash/nibble when cold or improved over mt82?
  6. Exhaust leak power loss

    It matters what scale the dyno sensor was set at if they used their own sensor. Or if some random PID was being pulled from the obd2 port by the dyno. Find that out first. If they stuck their own sensor on your car, was it free air calibrated first, where was it reading from? Tail pipe or bung...
  7. Question for guys who actually have the the Roush Kit

    Great info thank you for sharing @engineermike
  8. PCMtec

    Roush cals for gen2's up and running. Glad it was brought back up. Have been waiting for it to update on its own. The table and parameter volume is staggering. Taking time to get the hang of navigation due to the access allowed now. Knew there was more in the ecu... just needed ways to see...
  9. E85 worth it?

    Use the stock fuel line for the vac line to the radium hat when deadheaded.
  10. Positive KNOCKR when not using octane booster now

    How much timing change? I only ever saw 24 degrees na on 93 and what ever I wanted on e85. Never ran boostane until boost. No issues with 18.5 to 19.5 at 10psi with 4 oz or so per tank. I suspect I could get away with another degree but meh. It's already fast and no issues with this timing for...
  11. Positive KNOCKR when not using octane booster now

    The ecu can learn from past KR (similar to LTFT) but the tune has to be setup for it. If it's not, it will continue to knock everytime and rely on knock sensors to react vs learn. On stock settings, 2 to 3 degrees of KR will move the learning along very quickly. And it would progressively reduce...
  12. Problem with tune? fuel? VMP LOKI kit

    What's your style that they claim is the issue? Wonder if it's more the os used and only getting so much improvement from adjusting around the bypass opening.
  13. Roush to VMP

    I don't think it's worth 7 to 10 grand when pump gas will be your true limiter. Engineer Mike is great example of how to push on pump gas. More gdi flow has worked very well for him. 700whp is about the limit most see. This shows up pretty regularly at oem levels too. Better iat2 cooling does...
  14. 15-17 Whipple 3.0 looking for 800 on e85 - what pulley?

    overshoot with boost and pull a degree or 2 of timing on e85 if needed to limit. Just different way to dial in cyl pressure. At the end of the day, that's what we are chasing.
  15. Knock sensor/timing

    @Walkingdogs Thats in line with what id expect on 93 alone given local and head unit. I too use 4 to 5 oz boostane prof to get 97/98 octane and hold the tune around 18.5 to 19.5 depending on airload/temps. 10psi on a tvs. 1.6 to 1.75 airload depending on air quality. 19.5 at 1.6 and 18.5 at...
  16. Oxygen sensors going bad?

    Some am widebands do free air calibrations to calibrate. Couldn't we do the same with KOEO? Offset tables are present etc. would have to make changes to entire table as a whole.
  17. Extreme whine problem

    Drop sc belt and then serpentine if noise continues. Don't idle with our serpentine for very long
  18. TVS 2.3L Supercharger Made 830whp on a Mustang Dyno, 7499RPM

    What's iat2 look like after a pull or 60-130? Bet it hits hard. Love the 2.3 midrange. Even part throttle it's always present. Great numbers! What ring gaps?
