Awful performance after a month laid up.

Hi everyone.I've got a 2007 D3 tdv6 se auto which I haven't used for about a month.Today I went for a run in it and the performance is terrible, the last time I used it it was excellent.The previous owner had the erg valves blanked.It starts and idles ok but acceleration is awful.Does anyone have any pointers?
Thanks Geoff.

No it was a 60mile round trip everything seems to work ok but it was surging on the motorway as I tried to accelerate.

You could be right but I wouldn't know where it was or how to test it if I found it sorry. I've also noticed I've put this in the D4 forum by mistake not having a good day.

I'll check the turbo actuator as well this week. I've ordered some maf cleaner that should be here soon I'll let you know how I get on thanks for the help

Well the cleaner arrived and I gave the maf sensor a good spraying. It's definitely better mid range but pulling away is very hit and miss I've got to pick my moment before I pull out. I'll give it another clean as soon as I can and hopefully that'll do the trick.

I've got a basic code reader which didn't show any codes. Does the turbo come in as I move off from rest?I press the accelerator and nothing happens for a second or two then it pulls away slowly before accelerating very frustrating.
