Fat-Tony Member 5,364 Member For: 18y 1m 2d Posted 25/04/08 02:08 AM Share Posted 25/04/08 02:08 AM MYWPN is 100 percent correct. I could not flat change my BF and you would notice that there was a boost drop during the gear change. Torque management which is also done to the autos to protect the gearbox and stop the engine from OVERBOOSTING during the shift. I will assume in the manual it's done to protect the fragile clutch and prevent overboost on the factory tune. Link to comment Share on other sites More sharing options...
