Help. Golf running like a bag of nails

[JackM92]

I have a 01 PD115 which has the following mods:
130 turbo and injector
Intercooler
EGR delete and 150 intake
Straight through exhaust

The work was carried out by the previous owner and he only had a 115 remap done on it (Mobile service). I have picked the car up tonight and its running rubbish, Doesnt pull like it should and pulls back alot, especially in 4,5 and 6th gear.
What is the problem? Do i need a live map to smooth out the power and tune the engine to the 130 turbo?
There is a light on the dash, Looks like a coiled wire sideways, Looked in the book and it says the glow plug. Could this be causing the problem?

Thanks

Could be a sensor MAF? or boost leak.

Thanks.
Apparently the last owner had it on the computer and it came up as brake pedal switch.
Could this be stopping the car from running properly? and how much does it usually cost, needing done asap.

Not normally

You got any smoke coming out of the back??

[JackM92]

Yeah just the usual cloud of black smoke. Nothing un-normal.

Urm thats not usual.  You should get a little under load but that should clear through the rev range

Is the car spluttering??

Id say boost leak or maf sensor

[JackM92]

Yeah juddering a lot when I get over 2k really.
Feels like its got a load of flat spot through out the turbo, Hence why i thought of a remap. It will be completely dead then burst in to life for a second then dead again etc.

Get your head under the bonnet and follow the boost pipes and look for anything obvious like a pipe hanging off

Also disconnect the MAF and see if it drives any better

[JackM92]

I will have a look in the morning.
NOt sure how to disconnect the MAF, Il have a search and find out.

Thanks

Black smoke = definite boost leak somewhere along the lines.
