We’ve decided to discontinue the blog and put all of our tunes in database format for easier viewing. Check back soon!

At BrenTuning, we do not follow the basemap + tweak custom tune approach. We are constantly testing new tuning strategies based on changes to intake and exhaust cam timing for the 2008+ STi. Most tuners leave them alone and feel they are near optimized from the factory and boy were they wrong. Our latest and great tune is making stage 2 power with next to no parts on the newest 08+ STi without stressing out the car through the factory exhaust.

Below are the results of many mapped Mini Coopers we have done recently with great dyno results. Both the Mini Cooper S, JCW, and turbo versions can benefit greatly from a tune. Through correct mapping of fueling, advance, torque tables, DBW, limiters and boost mapping the Mini Cooper can really wake up and increase it’s low to midrange power extensively.
Mapping can be adjusted for larger turbos, injectors, methanol, and all bolt-ons etc. We are not a “canned” tune company. Also our files can be loaded onto DS flash handhelds for those who like to map switch or our not local to us. We have full access to custom tune JCW DME’s with no issues and read / write to all years while making live changes. Contact us today for the best for your Mini.
2006 Mini Cooper S JCW edition – otherwise stock vs tuned +30whp +42wtq
2008 Mini Cooper S JCW (Turbo) – stock vs. tuned +40whp +35wtq

Here are the results from the latest Audi RS4 file tuned locally on the dyno dynamics machine. This vehicle is equipped with the high revving 4.2FSI V8 found in the Audi R8. Many other companies sell files that simply don’t make power for these cars and are very expensive. We have found a mapping of specific tables most tuners leave out you can produce over 25whp and 25wtq on 93 octane dyno proven. The RS4 flashing process is lengthy but can be done same day. The RS4 utilizes twin ECU’s that need to be flashed one after another.
The test car below is a 2009 Audi RS4 with a GMG catback only.

Below are the results from recent dyno testing of a Mercedes Benz C350 W203 chassis equipped with our tune. This is the first model Mercedes Benz to use the 3.5L V6 power plant and is the same engine as still used in other MB models; W204 C350, W211 & W212 E350, S350, SL350, SLK350, CL350, CLS350, CLK350, ML350.
The car tested had a only Remus Muffler and was tested using CA91 pump gas on a Dyno Dynamics AWD Dyno. The power gains seen from tuning were very strong; +22wHp@5000rpm & +33wtq@3300rpm! As most of you know the lazy throttle mapping and torque management of Mercedes cars is geared towards casual driving and lack the spirit of a performance car. Through proper remapping of key engine parameters, the performance and overall driveability are much improved for a more enjoyable experience.
Below are the final results for our completed file for the Mercedes Benz S550 09+ ECU. For those looking to increase the power of their MBZ without loud exhaust modifications and catless headers – look no further then this modification.
The car that was dynoed was a factory stock 2009 model, running CA91 pump gas. Expect even better gains on our 93 octane file.
Maximum gains were seen at 2250rpm with +36.2wHp & +45.3wTq.
Peak horsepower figures were:
Baseline Max: 267Hp vs Tuned Max: 291Hp.
Peak torque figures were:
Baseline Max: 276.1Tq vs Tuned Max: 309.2Tq
Here are the results from a recently dyno tuned BMW E90 328i. The results are from the “off the shelf” flash (no custom dyno). 93 octane and custom tuning (especially with modifications) can achieve greater numbers. Changes made to the ever elusive valvetronic system, torque management, fueling, timing, throttle response and top speed limiter removal make for a completely developed ecu tune that was tested across many models, all firmware and software updates. BrenTuning’s specific 93 octane file will create larger gains then seen due to octane adaptation and higher timing targets.
The gains were: +15wHp@5200rpm & +19.5wTq@4100rpm (power to the wheels) running 91 pump gas with no mods. Tuning is also supported for the Si H.O. intake manifold 330 swaps.
Here are the results from the latest Mercedes Benz W212 E63 AMG tuning session. This is the same AMG engine as C63, CLK63, CLK63 Black Series, W211 E63, S63, SL63, ML63. The results were very strong and demonstrate what the “off the shelf” tune is expected to yield without custom tuning. Gains of +50wHp@6600rpm & +49wTq@4100rpm were seen on a Dyno Dynamics 4×4 dyno running CA91 pump gas. Gains are made through proper tuning of the fuel, ignition, torque limits, and throttle maps. The testing procedure involves the ecu being made accessible under front passenger wheel well. This flash and a catback exhaust has run a best of 11.6@121. Larger gains are seen with long tube headers, filters, or exhaust/xpipe modifications. This configuration with headers has gone 11.1@125.
These results are from recent dyno testing of a 2010 Mercedes Benz C300 W204. The C300 has a 3.0L V6 Power plant that responds well to tuning. We have files for both the California and federal spec ECU’s. Tuning is done through the BDM procedure. Allow 2 hours for programming. The result from ECU tuning were +12wHp@5100rpm & +21wTq@3050rpm seen to the wheel on a Dyno Dynamics Dyno. The car had no modifications and was running CA91 pump gas. Drive-ability is increased along with sharpness of the throttle response, shift points, and low end torque. It makes full a complete re-map of the C300 driving experience.
