well considering it was leaning out at 26psi, i think it would be unsafe at 28psi, unless im missing something.
im sorry but just because its a supra, and just because its a VPC doesnt mean it’s going to defy the laws of physics, and that it doesn’t function like every other system in the world. i dont need to be in your specific car to know its ghetto.
if you disagree with what i said about it running the same timing/fueling values from 30psi all the way to 43psi then say something. if you agree with what i said then stfu noob.
