Don't knock the 15/47 .... it actually INCREASED my top speed... with stock gearing, I couldn't hit redline in 6th... so.. that's all wasted RPM, and I was topping out at a radar verified 147mph.... with 15/47, I can bury redline... and hit a radar verified 154.9mph so... it has it's advantages.
I wasn't knocking it! I was just saying how it explains being to pull 12.5k RPM in 6th gear that's all.
