It's your vacuum lines.
Refer to Yozh's threads. |

Ya, probably they did not put the vacuum lines back in place correctly - or - one of your vacuum solenoids is bad.

Just curious, do you simply feel the boost is gone or is some app/diag showing zero boost?
Im asking because i dont really know how to recognize boost below 2k rpms.. If i push it, it downshifts to higher rpms.. If i dobt push it am i supposed to still reliably feel the boost? Sry im kinda noob in this |

What you might or might not have could be just some boost leakage.. ? (But from what iv gathered slower time might be caused by million different things so...) |
