I put a clutch in my car and did a full service. I had off most of my turbo piping. Before this my car would sputter a little around 6k now it runs fine till 5k then starts to sputter and won't run past 5.5. Do I have a leak or bigger issues? And if it helps the sputter around 6 showed up all at once it was so little I thought it was my clutch slipping now I don't know what to do other than try and find a leak.
