The owner of the M3 in question decided to make the switch to OE Tuning. He attended a recent dyno day where he saw the results of other cars and decided to try the OE Tuning tune. He was given a money back guarantee and after trying it decided to keep it. The results were posted and Powerchip as well as the usual suspects set against OE Tuning decided to attempt to discredit the results.
BimmerBoost in an effort to clear up this nonsense, which is what it is, contacted Jeremy from OE Tuning who provides his perspective below. Now, some things to note. OE Tuning moved their dyno to a new location. At this new location the dyno was loaded with different software and calibrated differently. Their experience is that the dyno now reads a little lower than it did previously. When Mike Benvo from Powerchip "infiltrated" OE Tuning in his effort to discredit them, Jeremy called up the owner of Dyno Dynamics to discuss Benvo's allegations which were dismissed with Benvo present.
This is all a waste of time as OE Tuning tells any customer to go use any dyno they want to verify numbers if they like. It is not in their interest to essentially lie to themselves. Any individual is free to take their tune and go verify it on any dyno they like, there is nothing to hide. Graphs below should with additional insight from Jeremy easily clear this up.
HP vs. AFR. base lines were run with a 20 minute cool down before running 4,5,6. This is to give the best possible baseline (which we used). I am a believer of “best vs. best”.
HP vs. Tq
best PC baseline vs. Gintani/OE Tuned runs. Tuned runs warm and cooled down. (a 15 minute cool down in between runs) Note also AFR has changed.
Dynos reads “tractive effort” and calculates other variables form these figures. Directly related to Torque output.
Road speed is spot on displaying same “ramp up rate”
