im thinking about building up a better motor here soon (all forged 355) and i was thinkin about switching to the vicor efi intake/rail combo with a sheetmetal elbow and a 58mm TB in hopes of making power past 5k, the car is currently speed density car. i was wondering what all i might have to do to keep the stock computer and avoid going to a DFI or similar EFI system. is this feasable or should i just go to a stealth ram type set up or an aftermarket efi set up?
