I just installed an Accel DFI Gen 7 w/ wideband O2 option in a 97 Z-28 w/ 383 LT4 stroker and ATI Procharger running 12lbs of boost. Does anyone know where I can find maybe a base tune close to my setup?

I don't really know what to do for tuning and I'm trying to learn. I know to start with the configurations injector size, displacement and everything. After that I really don't know where to go. Any help or direction would be appreciated.
