Ive moved your thread to a more suitable section.
Your going to be looking at a few things. First the turbo should kick in at about 2k rpm, is it not?
Second, could be a duff MAF, or if its going into limp then a turbo vanes or boost hose issue, let us know..

ive had all the hoses checked and had the computer plugged into engine management, this shows that the boost is working fine so still havent found the problem...
obv somehow power is being lost when the turbo kicks in, i have been advised to take the superchip off my car and then im getting the tubro stripped down to hopefully find the problem.
Initial thoughts are the waste gate not functioning properly....will soon find out!
Cheers

Turbo at 3500k?
**** me thats high, I thought it was like 1800rpm andnormally on diesels the power starts to taper off to towards 4200rpm (Until you have it mapped.)

3500 is way too high, all diesel power curves (mapped or otherwise) drop like a stone after 4000 rpm, diesel burns slower than petrol and higher revs don't give the charge enough time to complete combustion. Hence the masses of smoke out of the back of old-fashioned diesels at high revs, and the reason some remapped cars smoke a lot.
I'm guessing you have an AMF engine, which does indeed have a wastegate turbo and not a VNT device. The wastegate may be starting to act at around 3500 rpm, but the turbo boost should be felt from much lower down. Do you know if it is an AMF engine or some other code?
This is not normal behaviour for a diesel engine, and I'd have to suspect the remap first. What gain is claimed for the remap in power terms?

the superchip gives 30 bhp more
im guessing it has a wastegate, are there any common problems with the waste gate?

Ive got a customcoded stage 1 1.4TDI and mine still tapers of at around 4200rpm
and ye the turbo does kick in at about 1800rpm
