@GK1707 What duty cycle are your injectors @ under full boost on pump gas?
That I haven't actually logged (I need to take a WOT log some time soon so I will post it when I do).

Based on Fuel Injector Clinic and Injector Dynamics fuel calculators this setup with these injectors on flex would be around 75-85% IDC (I'll need to take an actual log to be certain how much duty I'm running) but that seems a bit much for my liking.

So I've been certain 1300 or 1700s would be safer for flex. When it comes to that point I may just bump up in turbo size also and move to an ELH.
