Those are some big numbers for a dyno dynamics machine. I have a 172mm pulley and green filters and put down 400 even on a 40 degree day. Others have put down a little over 350 on stock cars.
Looks like fun. Who were the HP and torque winners for the day?

Can you post the graph please? I would love to see the AFR if possible.
Thanks!

The motor torques more in the engine bay after the tune too haha
Methinks it will look strikingly similar to my graph, seeing as we've got the same box tune and stock pulley, and did pulls one after each other on the same dyno and the same day.
Edit: My AFR on the 472 pull was 10.9
As for comparison, not knowing how these dynos read compared to dynojet and mustang, a n54 135i with JB4, 5" intake [maybe AA?], downpipes and intercooler put down 331. No meth.

Thanks Doc!
So you said this was a box tune...as in canned tune? Not adjusted on the dyno? Very safe AFR.
Did you do the TCU tune as well?

At 10.9 there's still some power to be had, but I'm happy with that number for now. Getting greedy could be disastrous.
As for your edit, yes, I have the TCU tune which Jerry put on the car 2 weeks ago. It drives like a new car. I believe Jerry got some vbox data and or video of the pre-tune pulls a couple of weeks ago, and I'll need to grab his vbox for some "after" pulls to get some objective data. But I gave grant, shardul, and kauve rides in my car to get a feel for it, and they could tell the difference.
I'll let them comment. But I'm an extremely happy customer. I could feel the TCU tune much more than the ECU tune, at least from a driveability and shift-lag standpoint

Awesome Doc..Your torque at 3k is crazy!
I was wondering if the TCU tune is unlocking further power by eliminating load limiters, as I was under the impression a canned tune was worth about 25-30whp. Why does the M-Power dynograph say EC on it?
Thanks for the replies!

I'm not sure whether I got more power out of the TCU tune [changed rev limit, which could hurt or help depending where max output is delivered from this motor], but the drop in shift time from 2-3 and 3-4 is drastically reduced.
Not to mention driving around town it's smooth as butter.

I'm getting mine done tomorrow.

I for one could tell even as a passenger that the shifts were faster and smoother and made the car feel more planted. I believe Michael has his set to rev to 6800 RPM. No noticeable a$$ wiggling when Michael got on the gas either, just pure acceleration.
I'm getting mine done tomorrow.
