I'd guess unlikely. If you want to know for sure, datalog a full throttle pull and record injector duty cycle vs RPM. I've generally heard keeping IDC below 85% is ideal. I probably wouldn't bother putting bigger injectors in unless it's going past 90% for a significant chunk of the rev range or 95% at any point though.

The stock coyote injectors are 34lbs and work very well. You’ll gain nothing by changing them. Don’t swap injectors until power levels require it.
