meh, the TCU tune on the B8 S4 doesn’t seem to be lighting the world on fire. Going to slightly quicker shifts and a more aggressive launch isn’t going to change your life. Factor in the cost of switching at this point…you may as well spend the $2,000 on a weekend in Vegas, including some gambling and a very nice looking date. You’d smile more than you would knowing you could launch and cut a 1 tenth better 60’.
Also, running race gas isn’t so important in the real world. If you’re trying to set a time at the strip, that’s sporting, but personally I wouldn’t really care much about a race gas time. You’re not likely to run race gas while DDing your 191 inch long A6 sedan. Hardly seems important enough to worry about.
