Okay so these past 2-3 days I have noticed that my car has been feeling slower. Now when I WOT or slowly ease into boost I do not hit full boost until around 5k rpms. The car's power seems like it is being held back until 5k RPMS and then i can literally feel the car hit full boost and push me back into the seat. The weird thing is the stock boost gauge is working correctly and reading full boost at 15psi when I WOT or ease into it. I have no CEL so thats weird as well. This problem occurs in every gear but sometimes it will be random (like 1st-3rd pretty bad, but gears after seem better but still same bad) and so will the boost. Sometimes as I load into boost it feels like the boost is cutting out intermittent or like its holding back boost even though it reads 15psi. I am thinking its maybe the WGA (Watergate Actuator) or spark plugs or coil packs. I've replaced the boost solenoid before, as well as the full throttle body assembly. I have stock 02 housing, isr downpipe, tomei cat delete and catback. along with a turboXS BOV and just a filter cone instead of the stock airbox, no tune. 2013 6 spd w/ 157k miles. Could it be something with timing? Or maybe fuel getting cut off? Overboosting and ECU is making things weird? Or maybe the WGA took a dump like how my bov solenoid and throttle body did? Any ideas or suggestions would be greatly appreciated. Thank you!
