The Honda Prelude (1992) is an original car, equiped with a 2 litre naturaly aspirated F20A4 engine.
We exchanged the stock ECU for an Hondata ECU with which the fuell map and ingnition are optimized for the TORQAMP™.
The results can be seen in the graphs below indicating an increase of 23% up to 38% in engine torque and a wheel
power increase of 28% up to 44%.
The Subaru Forester STI is equiped with a 2.5 litre turbocharged engine.
The previous owners exchanged the stock turbo for a larger TD06-20G.
Due to the larger turbo, the Subaru's horesepower increased, though the turbo threshold increased as well.
As can be seen in the graph below, the turbo threshold is fully eliminated thanks to the TORQAMP™.
