I think they're something like $22-24K now (?). Anyway, the extra $$$ for their 'one off' 600 horse (600+ actually) is supposedly in the R&D to 'design' and dyno the 600 horse mill, switching to a Fast ecu (stocker supposedly isn't tunable), tuning that, blah, blah, blah. And there is no warranty on a 'one off' mill either - save for a "90 day" delivery thing.
But, in the meantime, Tiny has now posted the thread on HIS Smeding Performance mill! It's smack-on as far as what I'm looking for w/o any "R&D" costs...and 'comes with a 3 yr/unlimited mile warranty. Choose one. (Of course, any warranty is only as good as the outfit that issues it. So, who really knows whether that's any big deal or not.)
My big 'gripe' with the Roush 427 IR (aside from the h.p.) is the afore mentioned fact that its FI is designed to operate within set programing parameters and is therefore "not tunable by the end user" (supposedly). (I know one gentleman in ARIDzona who's none too happy with his 427 IR for that reason and whom I believe will soon be switching to a Fast control unit to fix that.)
I'm anxious to hear what Tiny has to say about his Smeding mill once it's installed and running!
