Temperature signal modifiers - They cannot give 15% to 20% bhp gains. They do make a small difference, but not in significant percentile gains.
Map sensor signals modifiers - They can better part throttle peformance, but again cannot give 15% to 25%
ECUs- Tuned for the specific engine, gains can vary from 5%(stock engine) to more than 30% (fully worked on, with all mods). |
