Guys i have a r33 with a r32 hiflowed turbo rated at 450hp and im using a safc2 for the tuning. the car made 200rwkw @ 10psi, i want to ran 1 bar and get around 220rwk. i need to get a z32 afm as it is maxed out as is, now my question is, should i get a power fc to replace the safc or just keep it, is it going to make a major difference if i get a power fc? i dont want to spend big dollars on a new computer if its going to make stuff all difference. thanks
