Yea I learn too, Im going to fit 74 throttle plus cold intake which will build myself, could you let me know what is the outer diameter aftermarket intake? Also I think it's good to wrap exhaust pipes as they are extremely hot and heat up the intake. After all modes do I need to remap ecu? As ecu has been designed for standard throttle body. Not sure Im not engine's engineer but if I replace the throttle body all sensors will measure air for small throttle body and I will have bigger so it will be around 17% more air so I can have problems with mixture???

Confused!
