I got the same road tuning work from Ed a few weeks ago, he did a great job and I'm currently guaging my fuel economy (that was the main thing he tuned it for as well as giving me power down-low on the RPM band. He definitely knows what he is doing and I would recommend his tuning skills to anyone. Plus the introductory price is very tempting. Thanks Ed
Here's the printout (sorry that was the wrong one here is the EQ proper), car has intercooler/radiator hoses, k&n filter, 2.5" exhaust, ECUtek reflash made:

We see about a 5-10% difference between the numbers on our Mustang dyno than using the road dyno feature of Delta Dash, although I can make that difference greatly higher depending upon elevation etc etc.
Nice numbers and curve!

The bottom line is that the car feels better in real-world conditions than how the graph looks or how high the numbers are on the mustang dyno.
Take a ride in it and you'll see what I mean...****loads of torque!

Long_Travel,
I'm not sure who tuned your car w/o a wideband previously, but I personally understand that the a/f values you input into the ecutek software are just approximations and can deffinately be way off in certain places. I take this into account and I also use other feedback to make sure my a/f is well on the conservative side. I'm not saying that a wideband isn't a great tuning tool... it obviously is. But there are good ways of getting close and staying conservative without oned... as per Duo's very resonable EGT levels.

Mike,
Thanks for the nice comment.
I realize that the road dyno numbers won't be a perfect match to your mustang numbers... or any other dyno for that matter, but I think given certain provisions, they should be on the conservative side.
FYI, I always use "very heavy smoothing" which gives significantly lower numbers than just the heavy smoothing mode. I also make sure to make runs on the same flat roads out here in davis and do a couple runs each way to make sure there really is no grade to the road... so far these roads have proven to be the flattest I've ever found
.But hey... we all know what really matters are the gains, not the actual numbers. It would be nice to be able to compare the road dyno numbers to your mustang though... maybe we can persuade Duo to make a couple runs at Gruppe-S
.Thanks

Like Ed said it's the gains that are important not the peak numbers, it's also how the car maintains it's torque. There should be no peak fall off.

BTW, I had my car tuned previously on the ATP dyno in Fremont and it made 216hp (very aggressive tune, now it's tuned for fuel economy which means 16psi is now 15psi at WOT and air/fuel and timing are turned down), which tells you that dyno puts out higher numbers than are seen on a road tune. The roads around Davis are flat as can be. Looks like the tune between our cars are pretty similar.

Though, shouldn't the max torque be close to where the RPM drops to when you shift, so after you shift you have the max power again?

Alan,
Actually while your boost is 1psi lower, your timing is actually a bit higher to maintain the same peak power as your previous tune was running and to improve low end torque a bit as well. You're correct in saying that the road dyno reads significantly lower than ATP's dynojet.
