| Location: | Canada, Quebec, Montreal | |
| Vehicle: | Toyota Supra | |
| Year: | 1989 | |
| Modification: | Lots, mega squirt | |
| 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. | |

| i have an 87 mk3 and it does the same thing...i was told i need bigger fuel injectors to match the air that my upgraded turbo is putting in. |
