Don’t expect much more than 330 WHP out of an E46 M3 without dumping a great deal of coin. Sticking to naturally aspirated power increases, if the motor has good compression, swapping for a catless header and a good 93 octane tune should increase peak power to roughly 320 WHP.

The Vehicle
Andrew’s car, the white 2003 BMW E46 M3 6MT, was the test vehicle for both baseline and B-Spec Tune dyno runs. It has over 170K miles and is a testament to the importance of being diligent with vehicle maintenance.
Dyno Facility & Conditions
The facility we chose to do our B-Spec Tune dyno testing was at European Auto Source, a very well respected and reputable BMW shop in Orange County, Southern California. Steve at EAS was our dyno operator for all runs to ensure consistency. The dyno at EAS is a Dynojet 224xLC.
How to Read A Dyno
A dynamometer, or “dyno” for short, is a device for measuring force, moment of force (torque), or power. In this case – we did two dyno runs: baseline and tuned. The difference between these two runs show the gains that the tune and headers provides.
Low End Power
You can see that at the lower RPMs there is not much difference in the power and torque, this is deliberate as we feel that everyday driving should be kept to OEM feel. We do not modify many parameters in this section of the powerband as there is not much to improve on in our opinion.
Mid to Upper Range Power
The mid-to-upper range is where we can see the significant differences between the stock tune and our B-Spec Tune over the entire powerband. This range of RPM is where track cars live and depend on. Notice that the stock tune falls flat at about 4.7K RPM – the range of RPM when you begin to feel the power tailoring off.
Conclusion
To put it all together, you’re looking at an average delta/gain of 24.68 whp and 18.95 wtq across the powerband. We draw attention to the average numbers because looking at just the min and max values can be misleading – you’re not just getting a 2wtq or 41whp gain, but rather a distributed power gain in the mid and upper rpm range.
Future Plans
Going forward, we expect to make some improvements to our tune as we continue to test and make adjustments to the tune as necessary. We are pleased to announce that Buildjournal will be providing free file updates for existing and future customers, both remotely and locally.
