top end speed

[scoott31]

Hi all new to the forum
I have a 2001 plate gt tdi 130bhp re mapped to just under 200 bhp. For the 1st 3 months every thing was fine. acceleration was great top end spped was hitting 140 no problem,  but i have noticed a lack of top end power when going over 120mph.
The car pulls up to 120mph no problem and from there on its very slow.
I  was told to get a boost control valve from angel tuning who re mapped the car, but when speaking to demon tweeks they have never heard of any1 fitting one to a tdi.
Could it be a problem with the mapping itself as the car pulls great up to this point and no slip from the clutch. or maybe the gearbox
Any help would be appreciated

Best bet would be to get it on a rolling road.  Does it really matter if it struggles above 120mph though?!?

With the state of the motorways and road up in the northwest i`m lucky if I can get up to a ton, i`d be getting worried scott if you car struggles to get over 20 nevermind 120

It doesnt matter that much just the fact it used to do 145 and now it doesnt makes me think something may be worng or starting to go wrong.
will try and get it on a rolling road.

Just out of curiosity other than the re-map have you had any other mods done on your car??
