Excellent information in this thread. I called Bill several months back with similar questions (and answers). In my case it was Evo/Gryphon vs. FU. I was glad to see it all reviewed and covered so well here for others with the same questions.
I have yet to order from Bill due to funds and because my project has been more involved than I ever imagined. I am currently just running a used Edge Evo I picked up cheap on Craigslist, but anxiously awaiting the funds to get a FU. I will continue to use my evo as a monitor (and probably have Bill convert it to a Gryphon for vanity reasons
).
My calibration code is NQW4 - anyone know if this is generally a good one or a bad one? I know I dont care for how it shifts in stock tune, although i cant tell exactly what its doing or not doing and when (as far as the TC is concerned). With the Evo tunes, the shifting seems slightly better but not as firm nor as "tow-minded" as I'd like it to be.
