Once I get a TBE (hopefully some day) I can say for sure if they fixed this problem. I have seem pleanty of cars running well without the port and polish and was just trying to say that it might not be as muchly needed as some have posted. Look at the mods they have done to thier cars (most are exotic) and had the E-manage as EM support. Things have started to change a little now that there is more info and tools out there but if you still feel you need it done I might atleast wait tell I'm ready to put on the TBE just so I dont have to mess around under there twice   |
No, the wastegate thing CANNOT be fixed with software. The size of the wastegate is physically too small to bleed off exhaust pressure without sufficient backpressure. Wastegates cannot be made to cycle at greater than 100%. The only way to avoid the boost cut is to turn boost cut off- which means that, with a good enough exhaust, you can reach more boost than your engine and turbo can safely handle easily. That's why Subaru put the boost cut into the system in the first place. Cutting it off is safer than letting it get too high on pump gas, especially our 91 octane crap.
