Somebody has to know the answer with what I am having with my Evo. When it was still stock, the car would pull hard when flooring it. Now when I got the P2 from Works and a cat-back exhaust, the car doesn't feel that strong anymore. It would boost to 20-21psi and stay in that area and not taper down but when it does that, my torque feels less. But when I floor it and try to keep the boost within 16-17 psi., the car feels strong. Anybody knows why? I already went to back to Works and they said the car feels normal with the flash.

 

what kinda blow off valvue do you have? have you reflash your ecu yet? Iwas kinda feeling the same with my car but after i got my ecu back the car feelt much beter i am at 22 or 23 psi 19 0r 21 when i want to be relax.

 

??? the p2 is a reflash.

anyway, i think you don't feel the initial torque as much because your powerband is smoother.

 

Whether if I use the stock or GFB valve the torque is the same feeling with the P2. Oh and the P2 is not a reflash, it is more of and agressive remap that the P1, well at least that's what Works claim. I think negativeB is right, the power curve is smoother, but I do miss that torque.
