long story short my turbo hic-uped. im going to deturbo (put the car back to Naturally Asspirated). All it has in the way of turbo parts is a "msd boost controler" (there's a vacume line running in from the TB and wires running out to the distributer) and a fuel pressure regulator, i dont think the cam timing has been messed with. what if anything do i need to do to get the car running strong as a nat. ***. (apart from changing the exhaust manifold)?

Go back to stock heat spark plugs. Crank the timing back up to 14* and run premium fuel.

cant i leave the boost controler in or will it advance the timing too much?

It won't advance timing unless your in boost. But it is easy to remove. Just disconnect all the wires and i think there's one you have to reconnect and cap the vac line.

I guess I fell into that one. It only retards timing (under boost).
