I was telling him about my tune, then took him for a ride in the 2500, he was a lil more upset after that, especially cuz it only cost me 300. But Justin is a stand up guy, he uses PayPal. I've talked to a few guys that have a tune on there 4.3s, they say they feel a large difference, but can still tell its a 6er.
