yip.. I understand the carbon build up, the Dodge ones I watched were "new" or clean.. mostly the one on my R/T that isn't driven to speak of. Just "raced" to it's low 12. THAT HAS TO CHANGE SOON! lol.. hate being the slowest FAST system!!! hehehe
I think Dodge just has slow electronics in general though, I know I have heard scary stories about processor time, or lack of on the PCM's themselves. FAST was a HUGE step up from that, and now the BS3 seems blindingly fast compared to the FAST in my R/T as far as action/reaction goes on sensor readings per change to program. Need more time to play with it, but it's pretty cool so far.
