I can provide more details
I agree with you, GM spent WAY more time getting all the details right and I'm not likely to get them as perfect no matter how much time I spend. Its much better to start where GM left off. In my case since its a nearly stock ls7... even more so.
100% stock LS7, stock ls7 injectors, stock ls7 intake manifold, stock ls7 Throttle body, stock fuel rail and fuel system. Literally total oem crate engine from a 2007 z06 and all sensors from the z06 as well. (ie: I have the oem ls7 map sensor) Any help to get me moved over and effectively started where GM left off would be a massive help.
Thanks!
