I am currently driving a satria 1.3 GLI. If I want to install an aftermarket RPM meter, do I have to get the signal from the ECU? Also, if I unplug the wiring to the ECU, will that mess up the programme in the ECU...
when you install a VTA External wastegate, do you experience boost creeps ??? as in boost increases as the revs go higher...
Do u need a boost controller to eliminate this...
