Boost on and off, car feels very slow.

After watching Spiderman 3 last night, I drove home and noticed my car was VERY slow. It felt as if I was towing something because it just didn't feel right. It feels like I'm driving on 2 cylinders.

Now I baby my car, rarely shift above 3, but I don't build full boost till around 3400rpm, and even then it feels like an on and off switch its not that smooth boost feeling.

I ran a boost leak test and the car came up with nothing, a little leak at the greddy RS bov, but I got that fixed. Whats wrong?

Im thinking spark plug wires, maybe plugs. Could be be something do do with the fuel- fuel filter etc.

How was the movie by the way.

what turbo are you running, it doesn't say in your profile that seams really high to be making boost on a t25. could be a problem with your waste gate...

Well my car has 180k on it, just turned 180k yesterday. How do I replace the fuel filter? Or how would I check that it is the fuel filter. I don't want to go replacing things that don't need to be replaced.

Also, yes it is a t25. I know thats a high amount of rpms to hit to fully spool but would that be boost leak or what? I have no boost leaks. So what should I look into?

Also, the movie, not going to spoil anything but I didn't like it very much, it didn't stick to one thesis. But it was well done, just way too much useless stuff. my 2 cents.

If all those things havent been replaced yet or in a while it might not be a bad idea. I know that when I had a plug wire go bad it felt kinda like what your explaining, but also after replacing them my car ran better then before the problem. Those three things I mentioned should just be replaced anyways in my opinion.

Have the same problem sometimes, and still haven't changed my fuel filter. I tried and worked on the top bolt for about an hour, and just gave up.

First I would replace plugs and wires though.
