I'm had the car (90 gt) dyno tuned for my last combo, which was a 331 stroker with 30 lb injectors and a factory ignition setup. I am putting a 347 stroker in with 42 lb injectors, a full msd ignition setup (6al, distributor, coil, wires) And I was wondering if the previous tune is going to mess with it, can I just remove the chip and it will go back to stock? I'm just trying to figure the safest way to run the car for the first 800 miles or so to get the engine and clutch broken in so that i can get it dyno tuned. Any info is appreciated. Thanks guys.
