My warranty is over and id like to go stage 1 with an grimspeed intake instead of the cobb intake. How do i go about doing a tune for the grimspeed intake if there arent any maps supporting it? do i go a stage 1 map and then get a custom tune for intake? any comments are greatly appreciated. trying my best to learn about the stages and what works best before diving into it
