ok, here's some more detail on my problem: when the car is not fully warmed up, it runs perfect-there is no jerky transition, everything is smooth during boost. once the car starts to warm up more, the jerkiness starts to get worse, and after about 10 minutes of driving, there is definite loss of power at full throttle at around 5 psi boost and higher. it's not so bad at like 3/4 throttle, but still there. my wastegate is set at 8 psi, which is more than i want to be running with the fmu, so i have been trying to be careful not to fully boost (btw is there a way to lower boost on an internal wastegate?). on hills at low speeds, the car barely has the power to make it up the hill because it gets caught right in the middle of the transition to boost and loses power. if you guys have any suggestions please let me know cause i'm out of ideas. what should my timing be set at? it's around 2 degrees retarded right now. also could it be something to do with my o2 sensors, like maybe one is faulty or the fact that they are side by side now instead of apart? thanks.
