Thinking about using a Fitech go street 400 throttle body with an EBL flash. Any reason why I can’t pair up the both left and both right injectors? Or is it too much load on the ECU? Running it on a L31 vortec with 7395 roller cam

 

Pairing both left and right injectors is technically possible, but you need to ensure the ECU can handle the increased injector pulse width and maintain proper fuel trims. With an L31 Vortec and a 7395 roller cam, tuning will be crucial to avoid lean conditions or drivability issues, especially at higher RPMs.
