460 EFI Guys: Megasquirt EEC-IV ECU. Here's the basetune applied to the flatbed 1994 460. AWESOME

I've always been impressed with what the stock eec-iv can achieve. But this tune with the eec-iv Megasquirt ECU is amazing. Your .585 roller cam is going to come to life with this. The lower rpm is going to really function well now also. I'm testing this at 5400 feet of elevation. This is a motor we built with our low profile throttle body, headers, 30 lb injectors, a healthy flat tappet camshaft, and our performance modified intake manifold.
