This is a good one. The '08 SE Catalog offers many Stage II kits. 113", 110" 103". They now even offer a 58 mm TB for '08. All kits "require ECM calibration (sold separately)", as we all know. Yet they offer no ECM calibrations yet. How can they sell these performance parts and not have ECM mods available? And dealers are installing these things, or even just mufflers and open A/C, without any ECM mods. Sounds like a recipe for disaster to me! 
Hoist! 
Hoist, I have a question or two.
I think some time back you listed that the TB on an '07 110" at either 46mm or 48mm. I think I saw someplace that the '08 110" now comes with a 50mm or maybe it was a 52mm, but either way it was increased in size from the '07.
Wouldn't this change to a larger bore change the AC backer plate and its bolt pattern? So an '07 backer plate would not fit an '08?
What size TB did you use in your recent kick butt upgrades?
Also in that "other" HD forum, I posted a question about Stage 1 and Stage 2. On that forum I see that 32 people have viewed it but I still have zero response.
I've been talking to people about this for years, or better put, I've been listening to them talk to other people about this. I thought that Stage 1 used to include bigger jets for the carb and maybe some AC upgrade. But with the advent of the electronic age, just about everything we do nowadays includes some type of electronic gadget that has to be used to get what we need to accomplish done.
So in today's electronic age, what is the a Stage 1 upgrade and what is a Stage 2 upgrade.
By the way, unless I missed it somewhere, weren't you going to put together a more detailed list of things you did on your motor and what the final results were and how you feel about the value etc per gain?
Thanks for all the great information.
