i looked into the efi option but instead i went for a cheaper option,(far cheaper) and got very pleasing results,
i bought a boost switch had i put into my charge carrier, linked up to my cold start injector, set up to 8 psi, cold star then clicks in addin more fuel, = allowin more boost, i run up to 21psi, and the car is producing 298 bhp, although that is with hell of alot more money in other area's of the engine
