I actually had to upgrade to 660s long before I maxed out the 550s because on pump gas, my 50 trim was maxing out the 550s, lol. So I am now running 660s, which I also get up too 100% on pump gas, but only ~80% on race. Now keep in mind IDC numbers are fairly worthless... I ran the 550s well into the 115% range and it went like hell. But for peace of mind, upgrade at 90% like everyone else does I guess...

Is it a myth that the S-AFC can help extend the injector duty cycle SAFELY to over 150%? And whats your plans , if any , for upgrading to 720's.
