as the title says, my boost fluctuates when i open the throttle 100%. it goes up and down from 16-10 psi. i have a new wastegate solenoid, new wastegate, new bypass valve (blow off valve), replaced the upper and lower intake gaskets, i do have the right size pill on the compressor side vacum hose before the t-fitting, all the vacuum hoses are new and are in the right place. i have even replaced the upipe, down pipe and installed equall length headers along with a cat-back exhaust. iv also added the cobb intake, perring turbo inlet, and have it set on stage 2 93 on the cobb access tuner and still the damn thing wont stop fluctuating. if anyone really knows whats up, let me know what im missing. and dont tell me the vaccum hoses are not right and dont send me the picture of cobbs "how subaru boost system works" iv seen it a million times, the vacuum hoses are fine and i do not have a boost leak because it boost past 19psi and will not fluctuate with a manual boost controller. Please help!!!!!
