| Problems: | The car has good air/fuel when its ideling 13, but when i start to drive and the car is under load it leans out to around 16. The car is built, lots of mods. Just installed an aeromotive FPR, because i thought it was lacking fuel pressure. Could it be the fuel pump not giving enough pressure under load? Its a walbro. The car was tunned and dynoed. it makes 336hp and 370ft-lbs at the wheels. It didn't used to run lean. Whats a good fuel pressure to set it at? Any help would be appreciated. |
