A dyno reading high will yield more power vs one that reads low.. For something so little as a ECU tweak, the results will be based per HP.
The % increase in power is how we should understand the difference or we adjust the power increase for a more accurate reading.

Of course it matters..

If you go to high reading dyno and make 1000hp stock and with a flash you make 1030hp.
Is the same as going to a low reading dyno and making 500hp stock vs 530hp with a flash.
You gain 30hp with the flash on both cases...

If this car made 400whp on the church dyno before, and 420whp after(5% increase) and you drove it to a dynojet and it made 380 before, and 399whp(5%), the difference is statistically unimportant. It is a fraction of a % difference. Run to run variance can be more than that on the same dyno depending on heatsoak, or any other number of factors.
Besides peak numbers we are going to see the power curve compared to stock, which is likely more important, and where most gains "should" lie if this device works as intended(big if..lol)
If anything the dynapak eliminates the variable of tire pressure, wheel size/weight, etc. That is like saying if you have wheels that remove 3% of your whp vs my wheels, your before/after is pointless.
Not to mention, this dyno is "high", that one is "low", this one "medium"... What is correct? Again, it doesn't matter. What matters is the gains before/after under as close as possible run conditions.
It is pretty much universally accepted that the delta is what is most important. You are probably one of the only people I have ever heard to try and argue otherwise..lol

Yea I am not sure why it is hard for you to understand. A dyno is a tool used to measure a gain or loss in power. You aren't comparing one number from one dyno to another.

If this tune works....I mean really works...I will give my ISF away. 
J/k but seriously I cant believe people actually think it will work. This tune box was a stolen idea and makes me laugh to think it will work. Oh well. Its entertaining none the less...

Lol every freaken tune thread. I'm doing this hoping to help out the community. If it works, wonderful; if it doesn't, ohh well. I'll try to get my money back then. I have always been wanting to dyno my car anyways. 107k miles lightweight rotors and wheels and tires; let's see what my car is still capable of making.

Although if you do it on a dynojet it is inaccurate because they read 10+% higher than a properly calibrated mustang dyno.
