TRM Tuning

We have had a number of inquiries about a few of the parts in play here.
My question to you is:
Are you interested in the parts being available separately, as a kit, or both?
The modified intake manifold blockoff (from removing the upper flap) is a "nice to have" but not required depending on how you are cutting up the manifold.
The 90MM MAF housing and intake tube some seem to want separately (though tuning is required to use it).
The grouping of parts is meant to work with a 90mm throttle body and 90mm 90 deg elbow.
Who wants to make the rest themselves vs buying all of it as a kit, possibly with a complete CAI housing?

📊 N52 Intake Manifold Comparison — Stock vs. Stock 🔧
Starting the data series with a pure hardware comparison:
Single‑stage (325) vs. 3‑stage (330) intake manifolds.

Each setup was run with its corresponding factory software —
➡️ The 325’s single‑stage used stock 325 software
➡️ The 3‑stage (3SIM) used stock 330 software

Same car, same dyno, same test conditions.
No tuning changes or external modifications — just manifold and software as they’d appear in their respective cars.

This gives a clean view of how the manifolds themselves differ in torque curve and airflow characteristics while using the original factory calibrations designed for each. (Hint: the biggest influence being the Valvetronic.)

Next, we’ll look at how tuning influences these same setups.
