While the problem with all of this hardly lies within the numbers, there is no control to validate the numbers. All of the gains are within the margin of the tune. There is a correct way to measure the gains and the process being used here is far from it.

Once again no one reads. Box was delivered empty and put into the mail box. Post office doesn't need you to sign unless over $400. They also market box empty with official stamps. The seller put a couple pounds into a box with no padding. Pads are heavy and busted out the side. Seller also didn't insure $155 brake pads for $155. He only took priories free $50. This is also something I NEVER do! If I ship you something there will be padding so the parts can't move and I'll insure for what you paid! Period.

So again by pulling timing which equals a loss in hp on almost all cars you believe the test is invalid? Interesting. I'll remember that. The cars running around 23 degrees of timing now. Clearly something's not right. My car with the same mods are running 28 degrees with the same ported parts. Only difference is cat vs catless. Clearly no one can hold on a week so forget it.

O and love how I come out and tell 100% what's going on and what I did but any big wig company says we did nothing or tells you nothing sometimes not even showing AFR and you all just take their word. I love the amount of pawns in this world.

No the test is invalid because you have no control. You've tested multiple cars, on multiple dynos, on multiple days, with multiple mod iterations, and you are trying measure improvements that are within the experimental error of temperature and humidity.

Get the car setup with whatever "cheap" exhaust you would like and then all in the same day, without unstrapping the car from the dyno.
Dyno chart 1) Baseline it.
Dyno chart 2) Tune it to whatever level the tuner feels comfortable with. A combination of fuel points, timing, etc..
Dyno chart 3) Bolt your mods on. Base line it.
Dyno chart 4) Tune it to the exact same level of aggressiveness as dyno chart 2.

The differences in 2 and 4 are the impact of the mods. If the mods allow you to run more fuel or timing without knocking? Great! Want to change the exhaust again? Or add an electronic fan in the intake? Or a flux capacitor? Cool, but you have to start at dyno chart 1 again.

But until you do this or something similarly scientific, you don't have ****.

very well said on how to take a more scientifically acceptable methodology. i mean if i ran a tune on my car i'd like to dyno before/after to see the differences for AF ratios, wtq/whp, etc... plus i can actually change my sticker to reflect that +hp that happened
