    I did find that bumping up fueling by 20% was fine for my swap. Not even 20%. 18-19% was perfect moving up from a great gasoline tune on the same hardware. I keep hearing this 30% figure and I know it's too much for my setup. My LT/ST fuel trims are always +/-10% and the delivered fueling always matches commanded according to my wideband. It's amazing how much power you can build safely with this fuel. $1.79/gallon today.
