Does anybody know if installing a dump valve will activate the engine management light?

Probably not if its the RIGHT one

It's an aftermarket one a mechanic I know said it did it on his vxr corsa so he had to have it mapped out

Yes it will I have a SSQV on my tjet 150. You have to leave the electrical connection on the oem one but fit aftermarket one on the pipe the car thinks its recirculating as input to ecu. My light only comes on when at low speeds as not enough boost to lift dv 1-3psi but enough to trigger p00039 fault code air bypass circuit. Leave it for three car trips turns off

Why do you want a dump valve? Custom induction has much better results

I've already got one on, but I wanna put my dump valve on as well
