After having it for a few days I have noticed that it is really down on power, so I threw a cheap boost gauge in it to see what it was doing and..Boost gauge only reads 0-2psi giving it the beans. Vac line for gauge is going directly to manifold where bov line was (bov removed).I've checked all the cooler pipes, gave the boost solenoid a quick clean and had a quick look at the compressor wheel... and I cant find anything wrong.Anything else I should check before shelling out for a tuner to have a look??

06/06/12 07:51 AM06/06/12 07:51 AM #8 Author Well I looped the vac line from compressor housing to actuator, still no boost. So tomorrow I will change out the actuator for my 12psi one, and check the cat... hopefully one of those things fixes the problems
06/06/12 08:17 AM06/06/12 08:17 AM #10 Author Well I'll be pulling the dump off tomorrow to check the wastegate, and be checking the cat.... I'm really hoping its the cat
