Bill Pemberton replied to the thread Blacksheep Creds.Your "Cred " here is monumental and those just finding TMO will soon learn why you are considered the " Tire Guru." They will also learn some technical terms and will eventually learn the differences between a wheel and a rim, ha! Your long years... (see full post)- stevbd replied to the thread Brand New Drivetrain - No Engine Braking.I suspect it’s the combined effect of a lightweight flywheel, clutch, and driveshaft, all of which reduce rotational inertia on the engine, plus the 3.73 gears which are forcing the engine to slow more quickly. All of that combined might make... (see full post)
mwjscn replied to the thread Brand New Drivetrain - No Engine Braking.So to start troubleshooting, does the behavior continue when the stock OEM tune file is loaded back in? (see full post)- Firefighter46 replied to the thread S197 BackInBlack.It's a matter of staying at it, and not losing interest and hope. Even at the OE level, with all our resources and "smart" people, sometimes conversations over beers on a Friday after a week of beating our heads against a wall did more for moving... (see full post)
- galaxy replied to the thread Brand New Drivetrain - No Engine Braking.The multiple file revisions were only to try and address the new issue. None worked. To clarify, the tune file that’s been in the engine for the past two years running amazing was not changed when these new symptoms started after the new... (see full post)
Junkyard Dog replied to the thread Dark Horse OEM Pad wear per track day - does this sound Reasonable?.Thank you. I can now find them at Ford online and at RockAuto.com. :thumbsup: (see full post)-
mwjscn replied to the thread Brand New Drivetrain - No Engine Braking.In your OP you state the car is Lund tuned with multiple file revisions?Since you said you did no hardware modifications to the engine that require tuning, flash the stock tune back in and see if you get Deceleration Fuel Shut Off behavior back.

- galaxy replied to the thread Brand New Drivetrain - No Engine Braking.I get it, but what caused it? What caused the change? Nothing on the engine/tune was touched.No, the pops and crackling is not part of the tune. Same file as before the drivetrain. (see full post)

mwjscn replied to the thread Brand New Drivetrain - No Engine Braking.Like GAR944 said, normal OEM behavior is that the fuel injectors actually shut off during off-throttle coasting in gear. You can hear the transition when the exhaust gains that subtle deeper rumble (it takes a mere moment to kick in once you get... (see full post)
GAR944 replied to the thread S197 BackInBlack.I'm sure I've said this before, fingers crossed for you mate. The perseverance you have shown chasing this is wild. Got to have a win sometime. 🙏 (see full post)-
GAR944 replied to the thread Brand New Drivetrain - No Engine Braking.Is the crackle part of the tune? Taking a total stab here. Excess fuel on over run, rather than fuel cut on closed throttle normally, with timing still firing before exhaust valve opening sufficiently to dump gases out exhaust. You are still...

GAR944 replied to the thread S550 Clutch is scratchy after track day.Exedy Hyper Single has been everyones recomendation. Depends on usage though. Yes its streetable, would i want to drive it in traffic daily, hell no. Its a firm pedal and bitey, very limited slip. No officer, i can't get it off the line in the... (see full post)
TheTed replied to the thread S650 2025 Dark Horse HP 6-speed.That's an interesting read (or re-read, I think I've seen it before). Ultimately, it's normally been dictated to me what is required by the organization/track running the event. I run a 4-point harness with a HANS (although I'm thinking I may... (see full post)- galaxy posted the thread Brand New Drivetrain - No Engine Braking in S197 Mustang Tech - GT, Boss 302 and GT500.So check this one out. Just finished up a project on my '12 GT replacing the entire drivetrain; McLeod clutch & billet lightweight flywheel, Calimer state 3 tranny, DSS one piece driveshaft, completely overhauled axle with 3.73 gears (from...
- galaxy replied to the thread Getting Boss - What to Ask?.And on that note...I have MGW in every hot rod I own. Recently I had the opportunity to drive my MGW in the 350 back to back with a buddy's Barton equipped 350. Gotta say, struggling to state I like the MGW better. I'm not gonna rip the MGW...

- galaxy replied to the thread Getting Boss - What to Ask?.Sorry guys, that’s my bad. It’s been quite the story, but ended up with a ‘12 LS with 469 miles on it. I have everything; owners kit, framed window sticker, cooling ducts, splitter, proper functioning red key, the works. (see full post)

TheTed replied to the thread Dark Horse OEM Pad wear per track day - does this sound Reasonable?.These were purchased from my local Ford dealer directly, I just went to the parts counter, told them the car, and they ordered them in through the Ford parts network. Here are the labels on the boxes:So if I had to guess, Akebono is the... (see full post)

Junkyard Dog replied to the thread Dark Horse OEM Pad wear per track day - does this sound Reasonable?.@TheTed - Where do you purchase them? When I go to RockAuto, the only Akebono brake pads are not for the Dark Horse Mustang.And in the interest of getting part numbers and all, is there anything on the box? (see full post)
