Bro, you're honestly doing it wrong, how can you tell how much you gained if you have nothing to reference too?
Yes power on a stock G is also nice and linear, what's your point?

I will be publishing the video and the dyno results of my setup. The dyno was done this morning on a Mustang brand machine. The guy had told me his dyno is the lowest reading machine in the area and the true results should always be in the 10% plus bracket. He had told me the guys with 370z he had tested showed 10-15% less on his machine versus the other readings.
As the general remarks the dyno guy was very impressed with the straight power climb of this car without some major power curves.
Watch for the video as soon as it downloads to my You Tube.
I was trying to search for dyno results of the other members to get some comparison snapshots of the printouts of Mustang dyno tests.

this.
If you didnt do a before dyno, for all you know, you could have LOST 10hp due to this mod. Dyno's are a tuning tool and all they will give you is a CURRENT snapshot of your car. If you have nothing to compare it to, you dont know if you have gained, or even lost, hp or tq.

This last picture illustrates this particular session. 275.5 hp to the wheels on Mustang dyno. Some people say the actual hp is up to 20% higher.
Watch the end of the video for final readings including the torque.

I'm sure there are Mustang dyno results for the coupe somewhere and they can't be drastically different otherwise it wouldn't make any sense to dyno test.

Were those 257 and 263 on that exact dyno with very similar conditions? If so then you might have something to go off of other wise it doesnt matter. There are too many factors involved to just compare to what other people have got. The exact dyno used, weather, altitude, if they had fans blowing on the car, hood up/down even the car itself. There's just too many variables to try to accuratly compare to something else.
I got mine dyno'd last summer. Averaged around 257 on a mustang dyno, but this was middle of summer with 105 degree temps high humidity and no fans going.

So what are your dyno readings gentlemen? I had 2 tests before [when I bought my car] but they were so low [ 257 hp to the wheels and 263 hp] I didn't take them seriously figuring there was something wrong with the machine. My friends GTI with a chip had tested 247 hp the same time.

Numbers from different dynos are not comparable.

Wow, I like the sound. I like this mod and I like what Greg is doing, experimenting, although however unusual it may seem.
There are tons of info on how to correctly interpret/use a dyno reading. It can be pretty lengthy but generally you want to have a baseline reading then another reading with the mods installed. Compare the 2 to see how much you have gained or lost after installing the mods. That's why people are saying the modded run is useless if there's no baseline to compare to.
So it makes sense that you want to do the baseline run and the modded run under similar conditions to eliminate all factors (or as much as possible) other than the modifications you've put on. This way you'll truly test the effects of those mods, while keeping all other factors (air temp, humidity...etc) as constant as possible between runs. All those external factors (air temp, humidity...etc) can and will affect the dyno reading.
Mike was referring to that dynos usually take into consideration of those external factors and correct the final reading accordingly. But it's always nice to keep track of the testing conditions for more accuracy.

The dyno should be connected to some basic weather module, that can compensate for relative humidity, air density/pressure (barometer), and temperature.
PV = nRT.
Higher pressure and colder air makes more power, given that all other conditions are identical, including the car and mods.
