Found a clue from Overboosting04, hope you dont mind at all.
here is the link
we have similar engine setup. but both car are running huge differences in power wise and i believe thats all down to fuel. one is the most ****ty fuel in this planet and the other is e85.
But on the 3rd page of overboosting04's thread, i spot he hits peak torque @6194rpm which is pretty much identical to mine. i know he's running 25psi which is higher. But my boy on the real street, it hits peak torque @ 5000-5100 rpm, which is 800rpm different from dyno reading.
actually im in hard time to do research on those ej207+gtx3076r because this kind of setup is not really popular in North America. so in this case, could anyone here help me out. i'd like to see more dyno printouts and learn the experiences.
p.s. i will try meth next week, maybe e85, lets see whats gonna come out right after.
