The Crossfire Limited has 215 HP, you will not gain another 20 HP from a chip. ECU tunes for our cars are not cheap starting at about $400.00 for a gain of 8 - 12 HP (and most are not dyno proven). A RennTech, or Startech MB tune will run well over $1K. Be aware our cars are not "tuner" cars and performance upgrades are very expensive, and there are not alot out there.
