So my buddy has an 05 srt4 with...maybe 7500 or so miles...not even. He is saying he is not feeling the power he used to...He says(I don't know what he is really saying, I didn't see it in action) it shows its boosting but feels like it isnt....I believe they checked for leaks, replaced plugs, all that little jazz....anything that could cause...I guess boost loss?....he took it took the dealer once or twice...they don't know. Any help?

 

You can put it on a dyno to see what it's putting out.....lots of things affect turbo cars.......gasoline to outside air temps.

^ what he said. It sounds like it's pulling timing and/or leaking boost. My car actually got quicker after 5000 miles or so.
