Maybe I'm reading this wrong, are run#1 and #2 reversed? 1 is supposed to be stock, and the other stock plus ecu and tcu tune?
what's with the bump? And why does your power drop like a brick after 5400 rpm on run#2?

It is backwards, not sure why he put it that way. And I was very surprised at the drop off, although the tune fixed that.
FWIW as a point of comparison..
I went from 412rwhp/452rwtq stock to 452rwhp/508rwtq.
I'm assuming the dyno operator did everything correctly? (e.g. right gear, dyno mode etc.)
Heard good things about this place. Looked like it was done right to me?
I was looking for something north of 400 after the base run of 379. Many have said upgrade the cooling, which makes sense. Trying to decide on what next. The IC pump most likely then either the h/e or split cooling which I am just learning about. Looking for a conservative approach as this is my daily I depend on.
Curious though how she would have run on a dyno jet as I'm learning the heartbreaker dyno runs low. Just don't know how much.
The mustang dyno is a hard dyno, it doesn't lie. As far as your cooling, as long as you stay stock ,get a good heat exchanger , an upgraded Bosch pump and split the cooling with a BMW reservoir. You will find everything you need on here via diy write ups.

IMHO - if you don't add boost (blower/crank pulley), a larger HE, Bosch 010 or Johnson CM30, and a split cooling setup - you will be fine. That's more than enough for a stock boosted car that isn't going for records and is a DD with some spirited runs here and there.
Also, I am selling my BIP kit that has everything you need to split the cooling - just haven't gotten around to installing it and simply don't have the time for any more mods. Let me know.
Something is still not right. If you look at the peak torque number, the only time you gained is at 3400RPM. Anywhere else, torque is actually less. (than old peak number)
Look at HP. between 3600, and 4400 you have actually less HP. Not that that is saying a whole lot, but it shouldn't be like that.
I really don't know anything about this stuff, so someone explain to me what that bump is? Is that torque management kicking in?

Actually pretty even until 4400 rpm, both are up after that point, hp on the pre tune (listed as run #2) drops off at 5400rpm but after tune stays up pretty flat.
Looks like gains were made primarily on upper rev range. Is that how it should look like, I donno.

The problem is not sure how far I'm willing to go on a daily driver. I'm leaning towards better cooling/pump & a mild pulley....hopefully that will be enough...or I'm just foolin' myself. Hahahaha

I agree with that, but my interpretation is that it is because there was something wrong with the first run. The rate at which the power drops on that run does not strike me as healthy.

Would have been nice if I had more data but as it was my 1st experience on a dyno, I wasn't aware how much logging was being done. Will def need more the next time! Which will prob be after whatever my next mod will be!
