Got my '06 tuned
Your a troll for believing you did 282whp on a "corrected to read high to keep suckers happy dyno"...nobody gives a crap about your friend, Ive seen some fox body Stangs go 10's with way less than 500whp so whats your point? Go put it on a Dynojet and dyno more than 281whp (cuz we all know Mustangs dyno read low-and you admit this one reads really low) and prove us wrong, if you do I'll paypal you the cost of the DJ pulls.
here we go again
When are you guys going to get the f###ing point. Dyno #'s do not mean
**** when compared with other dyno's. There is just no way around it. Dyno's are used to tune a car.
THE ONLY THING THAT MATTERS IS 1/4 MILE TIMES AND TRAP SPEEDS!!!!!!!! THOSE 2 THINGS SHOW A LOT MORE THAN DYNO #'s

i8cobra, if you say you can get to a dynojet on Thursday, then there is really not a whole lot else to say. Im not sure what you are expecting to get on the dynojet, but its certainly not going to be more then your mustang dyno. Im willing to bet, if they dont try and use correction numbers and such, that it will be much less. I guess its just harder because of your altitude, but then again, thats what makes your mustang dyno numbers such BS in the first place.
Alberto, Im willing to go halves with you for him to go to a different dyno if we are wrong.

If you tweak the MAF output (with an S-AFC or UTEC), the ECU assumes the MAF is dirty and reading incorrectly and tries to compensate. When you tune in speed-density mode with a MAP sensor, the UTEC actually takes direct control of the injectors so that the ECU can't compensate. I'm ordering my MAP sensor today.
Just to prove I'm willing to admit when I'm wrong (mark the date and time
), here's the Dynojet numbers...

251 whp. However, notice that my tune is in fact going away. I was making power to redline, but now it flattens out at 5500rpm.
Also, I talked to Doug and apparently he has had the dyno calibrated in AWD mode (since 90% of the cars he does are AWD) but he hasn't had it calibrated in 2WD mode. He said this might explain the high numbers. So, this is my schedule for the next week and a half:
Thursday, installing my JWT clutch and flywheel.
Saturday, installing my MAP sensor and map selector switch.
Sunday, tuning on Doug's Mustang dyno. Even if the numbers are off, I'd still rather do my tuning on a load-based dyno. Sometime after, I'll head back to the Dynojet to compare with the graph posted above.
Wednesday night, run at the track to see how much I can beat my old 14.2 @ 99.38 time by on street tires.

Nicely done, way to be a man about it
With the way you hp curve is flattening out i wouldn't be suprised to see you get in the 270's after tunning with the MAP sensor.
Your are definitely a man for posting this, and I respect you more for it. I wasnt really trying to be a jerk about it, just wanted to be sure that everyone understood, more so those who may be learning, about how false your original numbers were.
Do you have another graph though, of HP vs. RPM so we can better understand when your car starts to flatten off?

As you guys get to know me, you'll find I'm not an "internet tuner" or a "cheerleader". Been doing this for a while ('bout 18 years). I'd much rather be honest than right. This was my first time on Doug's dyno, but not my first time on a Mustang (I've used DJ, Mustangs and Dyna-packs). As for the rpm, it's kind of a PITA, but if you hold a straight edge on the HP line down to the rpm vs. speed line, you can look over and see the rpm. Power starts to flatten out around 5800 rpm and stays level to 7000 rpm. I'll have it sorted out by Sunday with some new numbers. I'll also have some near-stock numbers on Doug's dyno for comparison.

+2.....Dyno numbers create a lot of confusion, because certain shops feel the need to pump up their numbers to make customers happy. Mustang Dyno's when correctly calibrated with nothing artificial tend to read as low, or even lower than a Dyno Dynamics.
I am glad you took it to the DJ and cleared up the confusion. Still fairly good numbers for your mods.

as a utec owner i am curious to see what the outcome is with regards to going from the MAF tune (open loop) to the MAP tune. i am seriously considering going to this but i need to do more research first. i had my car tuned a while ago and the car does run differently now. climate temps are the same so the ecu must be recalibrating and effecting my current tune.
