I have stock ICs, stock injectors, stock turbos, JWT stage 3 chip, 0 boost leaks and run 15psi with no detonation running pump 93. I have noticed a hint of detonation during tuning the boost controller when it spiked to 16psi. I would think with massive ICs you could squeeze 1 psi more. I would say thats running the stock injector duty cycle pretty high though.
