I recently noticed that when I accelerate quickly I have less power and have more turbo lag than normal making my pulls a lot less satisfying. Based on my little bit of research my DV could be leaking because my car as 150k+ miles, but I was wondering if there is another part that could be failing because I don't hear my DV screaming over the spool of the turbo. Either way I will probably replace the DV, but please recommend anything, thanks!
