The factory programming is just not user friendly. Especially when it comes to your wallet. $500 bucks for a tune is outrageous and for what? 30HP? Kudos to Lantana for getting his swap to work but I'd hate to see what it ended up costing him. After ripping up the streets in my Talon for years this makes a lot more sense than trying to put the AMG 5.5 in. High power capability, reliability, and great gas mileage.
