I am a new member from good old SC near myrtle beach. i have a 2006 f150 lariat 4x4 with the 5.4, automatic, magnaflo catback si/do and have recently added an Edge CS that i got from a guy who no longer needed it. i like the performance it offers but it has only 4 levels.....1) stock 2) transmission only 3) towing and 4) agressive with min 91 0ctane required. i see the Edge CS can be converted to Gryphon tunes via the internet for a fee and i need to know more. it seems the Gryphon has more options, including 87 performance, 89 performance, 91 performance, 93 performance and the towing or fuel economy. what kind of problems might i incur changing to the Gryphon? thanks form a 50 year old power junkie
