The rods are pretzel sticks. Beat on it enough, and they will eventually succumb to metal fatigue. I have a 2010 with M90 blower, 5.8 psi + LT's = 425 rwhp /483 crank hp. The eforce was rated for 460 crank hp = 405 rwhp... if you want more than that, use LT's, = free HP.
If u want 465 rwhp, and no LT's... it requires 528 crank hp..which is a bunch. You only need just 1 rod to bend or break, then window the block, rendering it useless. The 05-10 cars with the FRPP whipple and the 11 psi high boost option, loads of those have busted a rod. The lower 9 psi whipple is plenty, and is still pushing your luck. Roush told me that under no circumstances to exceed 9 psi.
The stock E force starts at aprx 5 psi... and ends up at 8 psi at 6k rpm. That's plenty, add LT'S if you want more.
It's very tempting to go nuts with the TVS-2300, since it's capable of almost 15 psi. If you want it to last, keep it conservative. If you want lotsa pwr, rods need to be replaced, in which case you may as well forge everything. Sounds expensive, but is cheaper vs windowing your existing block, then replacing that with a forged eng anyway. pay me now, or pay me a lot more... later.
