Install & Dyno Testing the Tweetler 90mm Throttle Body + High Flow Fuel Filter Stage 1+ Power Kit

I DIY install an upgraded Tweetler Performance throttle body and 6.6 bar high flow fuel filter on the #audis4 25Quattro B7. But first, we look at the limitations of the stock air intake system to understand why adding a larger 90mm throttle body is beneficial. I go on a quick road review to get a sense of throttle control today, plus log how much air can be moved through the mass airflow sensor in current state. I also use dyno result from fall 2023 as a baseline of horsepower and torque, prior to changing the fuel or air intake systems.

Afterwards, I show how to install the throttle body with my own set of modifications to make the throttle look great around the existing ‪@jackalmotorsports‬ cold air intake system. The high pressure fuel filter is then installed with a short lesson on the 3 and 4 port fuel filters and how fuel pressure regulators function. The last change is using the Jackal Motorsports flashing suite to update my tune from 1 to 1+ specifically for this kit.

Finally, it's off to the dyno to see what power and torque is made on the updated modifications and tune compared to the previous session.
