What I was kind of getting at was:

If you have to lean out the AFC by 30% with 650s just to get the car back to normal then that leaves you about 20% of tuning on the lean side. The bigger the injector that worse you are going to have to go into the negative. With the MAFT in conjunction with the AFC you can zero out almost any injector size you are going to run and then still have 50% on the plus and minus side of the AFC for fine tuning.

If you use the MAFT on its own then I agree its just a matter of picking your poison, both are trying to accomplish the same goal. They just do it in different ways. I would feel safer with an AFC since its a lot more refined but on the same note its a lot more limited to how much fuel you can take out to compensate for bigger injectors.

If somebody can show me a 2G that is running 1000cc injectors with a stock ECU and a AFC I will stand corrected.
