Bob,

Yes, their performance chips are comparable to those from PowerChip, Upsolute, or any of the other performance chip makers. They typically cost less than the third party vendors (current performance chips for the Chrysler 300, PT-Cruiser, Prowler, etc. run a bit less than $300), they produce the same performance gains and everything is still covered under the Chrysler warranty. It's just a matter of time before the same kinds of performance equipment is available for the Crossfire.
