4th is correct, closest to the 1:1 drive ratio.

I'm pretty sure Wolfie has a manual (could be wrong though), 5th is 1:1 in the MT82

Interesting, I even thought 4th was the correct gear for a manual. That's what we always did with my Focus ST, I know a different car but I thought all manuals regardless were used in 4th

Nah, you want the gear that is closest to 1:1 ratio. You can see how over inflated the torque number is in that graph. Take a look at some of the others and you'll see fifth shows more realistic numbers for torque

At least that's how I understand it, no expert by any means haha

Cheers mate, that's good to know!

Just checked my dyno sheet and see that Rob Herrod run in 4th gear as well

My dyno was also ran in 4th

Interesting, would be good to hear David's thoughts. My last car was run in 4th (closest to 1:1), but I do not believe the coyote has an extra 160Nm over the L98

Edit: technically it was an L77, slight difference

Another thing to consider with running in 5th is your speed, to run it right out your looking at over 200kmh at full noise which can cause issues.

Hi David,
Here is the dyno sheet from the vehicle in question.

Hi Burkey

Great to see you went to Joe at Crescent Motorsport.
He does a great job and is extremely passionate and conscientious re all his work.
I suggest seeing Joe and organizing a run at WSID for proper timing and testing. I am sure he would be very obliging to come along to record some proper testing with you. You can even load your standard tune in while there and compare times.

In regards to the gear selection on dyno I informed all our Streetfighter Specialist Workshops to run the Mustangs in 5th gear.
This is a true one to one ratio giving no false increases in torque . As close to 1:1 as possible is generaly accepeted as how power runs are recorded.
The tuning does not alter only results on paper.

Hi Burkey

Hi David,
Just to be clear, this isn't my car. It belongs to a mate of mine.
As I said earlier, my intention isn't to disrespect either you or your company.
I'm just trying to find reasons why a car running your system (not tuned by you, but by an agent of yours) would suddenly lose its abilities/superpowers

The car in question isn't running your CAI. It was one of the cars that was fitted with the full system so that people could hear your exhaust in the Sydney area.
Frankly, if I had paid money for a full system and tune WITH power gain, I'd be fairly disappointed in the "real world" results that it yielded on THAT day when we did the stock vs SF comparison.
I say THAT day because on the day prior it felt like an animal. To the point where myself and JoshTypeX were seriously reconsidering if we REALLY need to go and spend money on a Whipple... It was THAT good!

So on the one hand, I offer a glowing endorsement of your product, but on the other, we are all at a loss as to why it just decided to lose the plot the very next day.
Is there some way we can log the cars data?
Is it possible that the tune somehow doesn't do its job if certain combinations of drive modes are being used?
I'm just looking for solutions and voicing this discussion on the forum so that we can ALL learn something.
I think you'd agree that the forum serves no function if it fails to educate people.
Cheers,
Burkey

Hi Burkey

The vehicle PCM tunes do have a wide variety of compensations that will take into account . fuel quality, air temp, barometric pressure , etc etc.
This means that PCM tune will protect the vehicle and act accordingly to all conditions, detuning and uptuning as it requires.
To test properly from one day to another we would have it on dyno monitoring all outputs with our logging equipment.
To try and test on road without any measurements is near impossible to give any calculated conclusions.

No issues at all in 5th gear.
Vehicle is running at a natural 1:1 ratio which has less torque implications on engine and gearbox.

Just placed an order for a set of SF ceramic coated headers, and 200 cell cats for my UK GT auto...

Have to say, David has been great to deal with, very patient and thorough..

Looking forward to getting these on the car:hail:
