Turbo lag

Ive been running the same tune for a year now, but lately ( last 3 weeks or so) its been very sluggish id just like to know what or where I should be looking. If I take off i have to almost floor it to spool the turbo once it spools it seems normal.

yep still possible... Kinda unlikely if it was just cleaned but just cause they say they clean it they might not take the care for getting EVERYTHING clean. Turbo making any weird noises? Poss MAP sensor prob, backpressure sensor?

More than likely the MAP or EBP sensor like Andrew suggested. Since you are going to be taking it apart here in the next couple of weeks, let us know what you find.
