Im going to be adding an intake to my 08 gt500 and its my understanding that this will throw off the maf calibration in the factory tune. I have a pro racer package and would like to adjust the transfer function to compensate for the new intake. Problem is i dont have a wideband yet to measure my air/fuel. Is there a way i can get it close? Like with a formula or something? I read somewhere that you can do 90/new intake size and multiply the transfer function with the result. Does that sound right? Thanks
