I have an 88GT (non California)(AOD) which I understand has speed density system instead of the mass air flow. It is stock. I want to start modifying it for mainly low RPM HP/eff. I'm wondering how far I can go with modifications, before having to convert to mass air flow. I have several injectors leaking fuel. I have aquired a used upper & lower stock intake; including the injectors (stock 19#). Is there any way to have the injectors checked before intallation? I'm planning on getting a 65mm TB/EGR plate & porting the upper intake to match. Is there anything else I can do to the stock intakes. I do plan on getting the phenolic spacer between upper & lower. What else should I consider doing while I have all this apart? Do I have an air silencer that I hear about? Can the speed denisity Volumetric Efficiency lookup tables be modified or in other words expanded for more radical mods?
