04 TT - boost lag during shift

[trevorradman]

I am a proud new owner of a 04 996tt.  It has 36k, and runs great, except for the lag.

 

It hits 1.0 bar, so I suspect a tune.  It takes about 2 seconds to build boost, and 2 second lag between shifts.  The lag feels like a bog, could this be a wastegate issue?  I come from the supercharger world, relatively new to turbos, but how much lag is normal?

 

Thanks!

Other than the tune, could you please provide more info on your car?  What other mods are there?  When was the last time you changed plugs/coil packs?  Cleaned the TB? or reset the throttle adaptation?

I do not know of any other mods.  I didnt know of the tune until I saw 1 bar.  I have not done any work to the car at all.  I just purchased it a couple days back.  It sounds like I may have a boost leak from all the reading I have done, making test plugs now!
