When to reprogram?
I'm gearing up to install my first set of mod's to my factory stock LT-1. Mod's will include K&N w/open lid, shorty headers, hi-flow cats, and Corsa exhaust. Should I reprogram after these mods or hold off?
My next round of mods will likely include 160 thermostat, electric waterpump, throttlebody by-pass, and possibly a HD aluminum radiator. Then lastly, the third round of mods.. heads, cam, larger throttlebody, etc...
My plan is to dyno test after each round and post the results for others to use a guide for their work.
