RE: 870 boost - hhow55 - 09-02-2022 Does yours have an exhaust pressure sensor? Changed mine the other day, and immediately back to full boost, on a cm 871 though. RE: 870 boost - Rawze - 09-02-2022 another thing to look at is the turbo rpm. if it is higher than normal the engine may hold back some fueling. Would be a sign of damage to the exhaust turbine, or possibly a plugged intake or exhaust restriction somewhere. |
