After considering a 2.80, I'm having second thoughts. With a custom tune, my warranty will be gone. The car has 3K miles. Plus, the cost of doing the pulley mod right is about $1,400 which includes S/C pulley, idlers, belt, plugs, H/E, custom tune. The dark side keeps tell me "go for it" you only live once while the other says "you'll be sorry", $10K for a new engine. I need some drugs to get rid of these voices.
