Hey guys, its been forever since I have posted on here but I have a question. My car is now at 80k miles and over time I have noticed that I am losing power. I use to boost around 17/18 PSI and now I'm lucky to get 15. I just cleaned my K&N today to see if it made a difference and it didn't help all that much. I know I need an oil change but its not like I'm going to get any power back from that. I've never changed out any of the belts in my car, do you guys think this would help me? Any advice would be appreciated, I want my power back

 

Could be a belt, could be your boost gauge. Mine never boosts above 16.5 and I'm on a smaller ring than you are, so I'm willing to bet it's normal.

 

even though i use to boost more on the same gauge?

 

I would start to shine it up starting with the tb, maybe some seafoam, new fuel filter, spark plugs, gaskets, polish the **** out of it even clean your intake tube, when you do your oil change use synthetic (if you always have, otherwise it would probably cause more problems), trans oil change? **** just gets old and dirty..., better grade gas if possibly MAY help, but never know, also check for vacuum leaks (sounds plausible). intake gasket. You will be golden then.

check for a possible exhaust restriction (cat)
