Hey John, nice to see you around! I was your very first tune when you moved to Cobb in Utah. Really interested in this turbo, I recently upgraded to a DB Super 16G from the vf39 you tuned and am looking at this for the next possible step. Really looking for a good all around turbo that will spool mid 3k and provide a safe 320+ whp to redline, from what I am seeing from these graphs this might be it! Does FP offer it without a IWG?
