In an effort to regain the lead in the bling bling spending wars between myself and Josh Smith, I decided to buy a sexy Bimmerworld Carbon Intake Box. I was looking for a slight advantage here with increasing midrange torque and at the same time, adding a headlight duct to get some "off dyno" gains. Ive run two events with this new modification and the car seems faster. True test will come in about a week at Nationals. Updates to come!
The dyno plot below is from an unrestricted tune that I have. As shown, midrange power and torque rises a good deal. The GTS3 detune pulls out the upper HP and leaves me with nice middle gains! Unsure what added HP effect the headlight duct adds but even a few horsepower is better than nothing!
