Have any of you done some tuning of the PSA (Peugeot/Citroen/BMW etc.) 1.6 liter HDI engine?
1. Where to locate the EGR valve?
2. How much can the fuel pump handle (HP)
3. How much can the injectors handle (HP)
4. Where to get a 1800 psi rail pressure sensor, that will fit?
5. Can the PDF filter handle 200+ hp or?
