Truck made 400 whp 460 tq on 11psi with 93 octane and no meth with a tiny bit of knock. What should i cap the power at for a daily driver?

Its a bone stock 4.8 in a 09 silverado w/35k miles

Kb racing turbo kit 76mm intercooled 3"turbo back straight through exhaust, snow meth kit, and a lvl 5 rpm 60e going in this weekend.

 

Also has 60# zr1 injectors and an aeromotive 340

 

Turn it up until it's a 7 cylinder.

 

With the fuel system and meth you are running, shouldnt be getting knock. Power seems a little low to me too for a 76mm and 11psi. What is your AFR and timing at? Im no expert but something just seems a little off.

 

Forgot to add there was a leak on the hot side when we tuned it first. The clamp from the manifold to the turbo was loose

 

And there was no meth on that run
