This is from a recent thread at m3post. Like usual, the mods and admins are deleting relevant content as fast as it shows up. I've got copies of most of what they've deleted, and I'll add it here as necessary.

This is coming from the two following threads:

This is a serious accusation and one that I do not make lightly, but there is no doubt in my mind that this is Gintani/OE dyno manipulation and it should be brought to light. Here are some quick mathematical comparisons/analysis with other tuners to illustrate how extremely unlikely a flat percentage increase in power across the board is:

Active Autowerke:



rpm % gain
2500 12.0%
3000 11.1%
3500 6.8%
4000 7.9%
4500 7.1%
5000 4.3%
5500 8.0%
6000 11.1%
6500 12.3%
7000 6.9%
7500 6.6%
8000 9.0%



GIAC (tune+filter):



rpm % gain
2500 8.2%
3000 10.5%
3500 4.0%
4000 3.7%
4500 4.9%
5000 5.9%
5500 5.7%
6000 6.7%
6500 5.8%
7000 6.3%
7500 5.2%
8000 6.0%



Dinan (no graph)

6000 3.3%
8000 1.8%



ESS:



rpm % gain
2500 5.3%
3000 5.5%
3500 4.5%
4000 3.2%
4500 2.5%
5000 3.2%
5500 5.7%
6000 8.8%
6500 5.5%
7000 5.4%
7500 4.9%
8000 5.2%



OE*:



rpm % gain
2500
3000
3500 12.0%
4000 10.2%
4500 10.3%
5000 10.3%
5500 10.3%
6000 10.2%
6500 10.5%
7000 10.6%
7500 10.3%
8000 10.2%

From Mike @ Powerchip

Just analyized the results and according to the data, it seems as if a dyno variable was modified inbetween the two runs which produced an inaccurate gain.

The first two graphs are cars that Jeremy dyno tuned himself from our Texas trip. You can see how the gain on the bottom end of the OP's new dyno is artificial.

Furthermore, the bottom graph shows the deviation. You can see that the third graph has an extremely low deviation and that further supports the presumption that a correction factor was applied, or an input variable was changed - causing the skew of the entire curve upward, instead of reflecting actual power related gains.

You can see the first two graphs have trouble with gain between 4000 and 5500, and then have a sizable gain through the midrange and top end. You can see the large gap inbetween the two curves on the third gap, which is not representative to how an M3 responds to tunes in that area. Also notable is that the largest increase in horsepower is between 4000 and 5500 RPM, which conflicts with the previous two cars that achieve their highest gain at later RPMs, and have the lowest gain at lower RPM's. The only thing that can explain this is an unwarranted correction to the graph to skew the results.

OP: Please let us know as we would like to schedule your dyno. Mathematically speaking it's impossible for the chart they gave you to not have been fabricated.

This one made me laugh from Jason the m3post Administrator:

No thread has been shut down. And we're not here to cover up things for vendors or sponsors.
HAHAHA. No, just many posts removed that had relevant content about the habitual fraud. No, that's not designed to keep the sponsorship money flowing
