That would be an indication of either an incorrect calibration or intentionally trying to mislead-which is exactly what I said before...you don't stop early on the base dyno and then pull further on the after.
That would be an indication of a dyno operator putting the trans in D and laying on the loud pedal without knowing what to rev the car to.

If he/she had the car in Sport mode, manually shifted to 3rd or 4th, whichever allowed a full rev range without running into the speed limiter, and then ran it to the fuel cut, it would give the full potential on the graph, which is what a dyno graph without tuning is intended to do, so that optimal shift points can be hypothesized.
 
The first run may have been stopped to early I just did as I was told but look at the line he put on the chart to compare a common rpm point...
 
Also the car was tested in sport but remember it shifts on its own when manually shifting so we had to let off before shifting. The tune bumped redline shift to 6800 so we could pull closer to that number before it grabbed 4th, which it did one run...

I will say this thing pulls hard in those high RPMs. Making passes on the highway is a breeze now. So long mpgs, it is just to fun revving it high.
 
My car revs up to 6750 stock. Not sure why your tune only bumped it to 6800? Dont they usualy bump it up to 7200? By the way whats the highest these engine can pull to without blowing up? I would say close to 7.5-8k?? My car seems to pull hard all the way to the limiter unlike other cars I had where you can tell engine runs out of breath 500 rpms before redline... by the way the dyno numbers look good, its not all about peak numbers. U gained pretty good power through the powerband.
 
Also, I'd like to point out that below 4k RPMs on the base line tune I was not flat out as it would downshift. I had to roll the throttle in to flat out around 4k or it would grab 2nd. With the tune there was no downshift, it would hold the gear chosen.
 
I would like to see the numbers in a 4th gear pull since that is our 1:1. Would be nice instead of the 3rd gear pull. Still like i said inpressive gain imo

I like how all the "competitions" tune guy put there .02 in on how everything is wrong about the dyno LOL
1) I tune for 7500 but why take it that high when 99% of the time most run there engines from 2000 to 6500 why beat on the engine to 7500 just to do it

2) The dyno shows the gains I did 3 base line pulls and kept the best of the 3 , engine temps were the same on each run as the owner of the car on my dyno does the driving and he will tell you I held his up a few times till all temps where the same

3) I use 3rd gear so the speeds and the lingering going through the RPM dont put extra ware and tear , as long as all the dynoing is in the same gear the results as what they are , yes 4th gear would show slightly better peek # but there again I want engine safety first

4) I put the line in the dyno to show the gains because the peek # would be off as we took the tuned dyno further up in the RPM to make sure things were safe , I dont care much for peek # as you there maybe 1% of the total time you will own the car , I want good idle , better daily driveability , better over all performance and then peek #

The dyno is what it is and by driving it the owner tells he feels what the dyno shows , as long as the customer is happy with his tune I am happy with it as well

There was no manipulation with the dyno its all there and anyone that knows how to read a dyno can see it is a correct dyno and the gains are what they are and why the line was put just before 6000 to show the gains knowing the peek # the dyno gives would not be fair , make of it what you want , that doesnt change what the gains are from the tune and I dont change your DCT strategy from what it was from Ford and you cant change it back , this is a hugh red flag when you go for warranty

I wish you took it up to 7500 since that is what you tune for, so we can see where the power starts to fall off. Seems to me like it pulled nicely up to where you stopped.

Edit: Did I miss what octane this was on?
 
I'm about to go against a MS3 automatic with a custom turbo, i'll tell you how it goes.
MazdaSpeed 3? Automatic? Do you mean Mazda 3 with automatic and a custome turbo? You will get destroyed.
 
I have a K&N CAI, FSWerks Stealth exhaust + headers, and Tom's tune. I'll get a clip to you guys when its uploaded.
Nice set of mods! Is it a 5speed? Can you possibly get some 0-60 or 0-100 vids? I would like to know how much faster the car is with the mods so I know if its "worth" spending that much money lol. Since this is my DD that would be about all I would want to do for performance modifications anyways. Will be putting a ST exhaust instead of FSWerks. I like my cars as quiet as possible.

Your post is ignorant. Clearly you didn't read the thread because I never once bashed on your tune or process. I commented on the low numbers and that was it. It was your guy that called the chart misleading-not me.

I called it for exactly what it is-a dyno that wasn't pulled to redline. Considering the fact that it wasn't pulled to redline, a person can't speculate on what power 'may' exist there. It's your guy trying to speculate-not me.

Clearly I've stood up for you too many times. This was never an Injected versus SCT or Tom versus Aric. You are the one making that accusation/conclusion-not me.

I don't need your reasoning or excuses as to why you aren't doing pulls in fourth gear because RDC is the business trying to prove why it's 'wrong'-not me.

I already explained the process, you're just trying to justify it. Unlike you, I didn't come into this thread to start crap as you did with mine. I saw the numbers and commented on the fact they were low-that was it-until someone wanted to start imagining what may or may not be there. The fact of the matter is that we don't know because the test wasn't done that far.
 
So correct me if I'm wrong but doesn't a dyno compute HP and torque by resistance so why would it mater if it were in third, fourth, first, or even reverse? The trans is just a torque multiplier to get the car moving. Any links on how a dyno works?
