Speed density is a tuning method of using manifold pressure and intake temperature to calculate the airflow of an engine. The Rampage Fabrication & Design speed density kit is a plug’n’play option to add a TMAP sensor on the charge pipe of your GTR thus relocating the IAT from the MAF and eliminating the need for it.
- More accurate intake temperature readings
- Run higher boost levels
- Run larger mafless turbo inlets
- Allows use of vent to atmosphere blow off valves
- Vehicle will still operate if a charge pipe comes off
