Well to start things off i have a boosting problem on a stock EVo 9 MR, i cant really find anything about people having problems with boosting with stock evos, maybe im the first. SO, i have the small boost gauge in the cubby hold, and when i first started flooring the car about a month ago the boost gauge read 1.3, now when i get on it, it only reads around 1.1 and then drops dramitcally down to like .8 or something, around like 5000rpm. I definetly cant be boosting as much as i ahve been before becasue i dont even feel it when im drivving anymore, I dont feel the throwback that i felt around a month ago. IF any of you guys have na idea on what it could be, maybe its my piping or maybe it something more serious please let me know. And if this is a repost then if you can please link me to site where you found this, I would real,ly appreciate it.

 

I think when you first got the car you were amazed by its power when you first floored it, now that your driving it daily you're just more used to it.

Also buy a nice boost guage and mount it on your pillar.

Just my .02

 

Have you taken it to the dealer?

 

turbo leak?

 

boost leak and/or bad gas.

 

you guys think he might have leak in is pipes or a bearing?

 

Sounds like a boost leak to me. I would check all your pipe connections, they do loosen up over time.

 

Could it be a faulty boost soliniod or something like that? Wastegate not working correctly? Could be a simple boost leak. I for one will replace all the hose clamps with T-bolt clamps soon after I get it

 

I am taking it back to the dealer on tuesday, should i jsut tell them to give the car a boost leak test. Or what do you guys think i should tell them. Thanks to everyone for all the information

 

Same thing happened in my WRX and it was a boost leak start there, it was the pipes

 

Is ur MR stock? You have an Aftermarket Boost gauge? Might want to check the lines again.

 

Tighten everything you can, and if that doesnt work take it to the dealer and have them run a boost leak test (since its free). Your car is still stock right?
