so im in the process of building a fuel injected 351w based 408 stroker for my 95 mustang. Im looking to get about 450-500 hp that's the goal. I was wondering will I be able to run the stock computer with a chip or will I need to buy a whole new computer/harness? this is somewhat of budget build but I also wanna do it right if I could get some tips or help id appreciate t thanks
