Heads, how much gain?

Just be happy with what you have if you don’t have $3-5000 worth of play money to dump.... which it doesn’t sound like you do. Let the people who have play money chase every 50+ horsepower. The next guy will always have more time, $, and Hp anyway... not that there is anything wrong with that. Besides... you can’t just upgrade one thing. One upgrade always leads to complications up or downstream anyway. I totally get it, but just my .02.
