Hey guys! I’m the second owner of an immaculate Japa Import 05 wrx sti. I bought the car a year ago with 39,000 original K’s on the clock hence why I’m always worrying about it😂. Long story short, I bought this car off of a 75 year old in CHCH he had put a “RAGE” exhaust on the car. Took her to the local Subaru dealership today for a service and the head mechanic told me that I’ve got an aftermarket cattless downpipe hence why my heatshield for my turbo is gone and this is probably the cause for the 22psi peak However in third gear if I WOT between 3.5-4k rpm it shoots upto 19PSI and holds there as if my car is really pushing 19 PSI. The car is now on 55,000k’s I get it serviced every 5,000k’s, check oil and coolant every Friday. And I can literally count the amount of times I’ve boosted first gear, she’s never been launched and I always wait till she’s warm before going over 3k rpm. Is this high boost level anything to worry about? Or should I get it tuned either to support the 19PSI or to lower the PSI to make sure she’s running safe. Just want what’s best for my subie 😊 TIA
