Hopefully this is a pretty simple yes/no question (and my apologies if it has been covered multiple times, my attempt at searching came up inconclusive)
I have a '97 S10. 4.3 RWD with the 5 speed. I purchased an 0411 PCM from a member of the s10 forum which had already been flashed via EFI live to a 2003 s10 4.3 tune.
I've been working on learning how to tune this 4.3 that I have mounted a stock Syclone/typhoon turbo and manifolds to, just installed an edelbrock 2114 carb intake I converted myself with 42 lb injectors and an early LS throttle body, etc.
Inevitably like many people that have gone the route I have, I may be interested in a GenIII LS swap.
Since the type of engine is selectable in my tune file, would I be able to swap to something like an L33 and retain my current PCM without using any additional credits?
