I recently purchased a 2005 WRX about 5 months ago and it has always pulled great up until two days ago. I put it into second gear, was at 3kish RPMS and gave it all the gas by the time I hit 15psi and 5500-6k rpm’s the engine felt like it wanted to stop, almost felt like I kicked the clutch in...

On my way home from work i noticed i was only making 7-8 PSI. I then did a pull to see if i could make 15 PSI like i usually make, but had no such luck, still only made 8-9 PSI. Reasons boost cant hit values it should be able to?????

I have been having really annoying issues with boost spiking/control/stability. It has been going on for a few months and I feel like I have searched every corner of the internet for a possible solution so I finally decided I'd ask here. For context: I have a 2002 WRX running a Cobb Stage 2+...

2004 wrx here, so when I’m in 4th gear or like 3rd and I start to open the throttle pretty quickly at a steady pace I would say like 70% the car simply will just shutter and slowing climb trying to go past 3500 rpm’s And during this the air to fuel ratio is at 8:1. Almost like it’s just reached...

Hey all first time poster here, I have a 2010 wrx with a turbo xs catted downpipe that is otherwise completely stock. Over the last couple weeks I’ve been noticing that the car has trouble building boost fast but still hits peak boost. I’m not sure if it’s a boost leak as I’ve done a smoke test...

Hello all, I am extremely new to the Subaru world. I have always loved these cars since I first seen it in 2004. I just recently purchased a 2004 WRX Impreza Wagon. It's not perfect, definitely will need some love which I intend on doing. I just had this recent issue come up. When starting the...

Hello, I'm about to purchase a 03 Subaru Impreza wrx. In the description it says the owner tuned to boost pressure to 15 psi, is this a safe pressure or will it wear out the internals faster or damage components. Thanks for replying in advance

Hello everyone, I just purchased a 2105 WRX with ~85,000 miles. The car is in great shape and only has an aftermarket intake. While driving back home on a 5 hour drive I noticed that when I go full throttle in any gear there is a hesitation in acceleration. The car either bogs down or the power...

This is driving me nuts. I usually shift at 3k driving around the city with about 20% throttle and never fully get out of vacuum. Is this the case with everyone? Looking at my logs the closest I get is -0.9. Seems like I should be at least seeing 0 no?
