TRM Tuning

📊 Modified Single‑Stage Manifold vs. N54 & 3‑Stage (3SIM) 🔧
Just wrapped another dyno session — this time testing a modified single‑stage manifold.
The large throttle body and TRM 90 mm MAF were left in place for consistency with the last N54 and 3SIM tests.

Graph key:

Solid line → N54 manifold
Dashed line → 3‑stage (3SIM)
Dotted line → Modified single‑stage
💡 Key results (3000 – 7000 RPM):

3SIM leads under 4000 carrying strong low‑end torque.
The modified single‑stage is strongest from 4200 to 6600 giving an excellent overall powerband.
N54 manifold only pulls ahead past 6500 RPM.
All setups were run beyond 7000, but peak power occurs well before in every case.
This modified single‑stage balances airflow surprisingly well — sitting between the 3SIM’s low‑end grunt and the N54’s top‑end pull.

📊 N54 vs. N52 3‑Stage (3SIM) — Both Tuned 🔧
Next in our intake testing series: the N54 intake manifold compared against the N52 3‑Stage (3SIM) — both running dedicated TRM tuned calibrations for each setup.

What the data shows:

The 3SIM delivers stronger low and mid‑range torque thanks to its variable runner design and dual DISA valves.
The N54 manifold, which actually has a smaller plenum, only shows a meaningful benefit at higher RPM, where its shorter runners shift the powerband to the right.

💡 Next up:
We’ll increase the rev limit and re‑dyno with both the 3SIM and N54 manifolds, plus start incorporating modified stock manifolds to see how they compare.
This next round should make the differences above the standard redline even clearer.

📊 N52 3‑Stage (3SIM) Manifold — Stock vs. Tuned 🔧
Continuing the N52 intake comparison series — this time, the 3‑stage intake manifold as found on the 330.

Each run here used the 330’s stock calibration and then TRM’s optimized software developed for this manifold.
Same car, same dyno, same day — only the software changed.

The results show how the TRM tune sharpens torque delivery through the mid‑range and extends power smoothly at high RPM.
This tune fully leverages the 3SIM’s variable runners and both DISA controls to make the most of its airflow design.

Next up, we’ll overlay all four plots: single‑stage and 3‑stage, both stock and tuned.

📊 N52 Single‑Stage Manifold — Stock vs. Tuned 🔧
Next up in the series: the single‑stage (325) intake manifold — this time comparing factory stock software vs. TRM’s optimized performance calibration.

Same car, same manifold, same day. The only change here is software.

This shows how much power and torque can be unlocked from the stock single‑stage setup through careful tuning alone — no hardware changes required.

You’ll notice improved torque delivery through the mid‑range and cleaner power up top, matching the airflow potential more effectively than stock calibration allows.

This serves as the tuning baseline before we move on to the 3‑stage manifold (3SIM) comparison next.
