The more mods you do to these cars the bigger hole you dig for yourself.
Unless you have an aftermarket computer like a FAST, there is no dyno tuning.
These are not LS1, 5.0, etc that are dyno tuned. You need to get someone who specifically knows the car, get a scantool like a scanmaster at the very least.. matching chip/injector.. and figure the car out at very low boost. And low boost to match the octane in the tank. Or you'll be doing gaskets or worse very soon.
Start the reading.. first mod on these cars is a scanmaster.. period.. and then learn to use the tool.
