I'm asking because I'm thinking about upgrading to the turbo tweak 6.1 chip when I get a wideband a that chip requires 60 lbs injectors. I know my 42lb injectors are big enough for mid 11's which is my ultimate goal. So is there any downside to upgrading to the 60lb injectors? Fuel mileage? I always read everyone recommends using them as the last injector upgrade you'll have to make .
