I’m diving into the world of EFI turbocharging for my Ford 300 I6 engine, aiming to boost the power of my classic 69 Ford 250. I’ve already sourced an OBD2 mass air EFI setup, intrigued by the performance potential often associated with OBD2 systems, especially after my positive experiences tuning OBD2 4.6L Ford engines. However, I’ve noticed a trend in online communities where the 1996 OBD2 mass air system for the 300 I6 seems less favored, and I’m keen to understand why. This system appears to have desirable features right out of the box, features enthusiasts often upgrade to in older systems.
My main question revolves around tuning this setup for a turbo application. Coming from naturally aspirated (N/A) tuning, turbo tuning is a new frontier for me. Could Best Obd2 Plug N Play Tuners, designed primarily for N/A engines, be a viable option for custom turbo tuning? Brands like Hypertech and Edge Evolution come to mind as readily available plug and play programmers. With an air-fuel ratio meter and scan tool at my disposal for monitoring, I’m wondering if adjusting the fuel curve with a plug and play tuner could be sufficient. Perhaps I could even lock the timing to a fixed setting, similar to my carburetor-equipped 68 Ford, to manage timing advance under boost. Ultimately, my goal is to reach a similar power level to my 390-powered 68 Ford, which produces around 425hp, from this turbocharged I6. Understanding the tuning path, particularly regarding best OBD2 plug n play tuners, is crucial as I move forward with this project.
