Hey guys, so I am rebuilding my engine, and changing a lot of stuff, including doing the mass air conversion. I am really interested in tweecing. Just wondering as I am doing the build, is there a way to start tweecing, while the engine is out of the car, eg. I need a new eec for the mass air conversion, so is it possible, to program one of the settings on the tweecer, to the components I know I'm adding, eg. I have read that you can change things for stuff like injector size, cu in., information regarding mass air meter size, new heads, cam, etc. I am stroking my engine to 347 and upgrading the h/c/i, and fuel delivery including injectors, so wouldn't it be better once I'm finished with the build and getting the car back together, to have a setting already set up on the tweecer for the known changes.. What do you tweecer guys think?
