Hi all, just wondering if I can install a TRD SC with no piggy back ECU or upgraded fuel pump. Thoughts?? Thank you!!!

The engine may run lean under wide open throttle. If you're not getting enough fuel into the engine you won't make as much power as you could. The dodgy way to compensate is with a rising rate fuel regulator which will up the fuel rail pressure. The ECU should be able to compensate when running closed loop when you're cruising.

I'm not familiar with the TRD kit. It may have an additional fuel injector to provide additional fuel. If it does, you'll need some sort of box to drive it.
