First off, it needs to be the monochrome Evolution. Not the CS, CTS, or the older handheld programmer. So, it should look like this:
Converting the Evo to the FICM programmer is kind of a one time deal. After you're finished with the FICM end of the deal, the unit will be reset to stock so you can use it as a performance programmer.
You'll have to pick either the have the inductive heat or not. You also won't be able to switch/revert back to stock. You're going to pay regardless of whether you like it or not, but consider this.... I've never really seen any advertisement for PHP other than webforum sponsorships, and there is a HUGE wait for the FICM programmers. Something has to be working. They are getting constant customers for their FICM programming and it is likely all from word of mouth. Even if your pickup's response isn't real noticable, its a chance I'd be willing to make.
About the question on pilot injection, you're going to have to ask directly at the source there. Best bet would be to call and talk to Bill. They were(and still might be) having phone issues so it might be hard to get a hold of them.
