yep looked fine, 89%, just changed it for a new one, and started getting over 200bhp as you shoukd

The way its been explained to me is that the load on the n75 should initially be high, then drop and then will come back up as the turbo runs outa puff
Mine usually goes 95% > 75% and then climbs back up slowly, someone correct me if im wrong.

Correct, some tuners will initially jam the WG shut to aid spool up. High (95%+ duty) loads across the range indicate your requested boost is either too high for the turbo you have....or you've got a boost leak.
Dude, replace all of the crappy braided hoses, tighten all of your hose clips and stuff and then re-log. 4th gear is a much better gear to log by the way.
Can you remember what Boost/Timing settings were applied to your car when you had it mapped?

Just replace ALL vac hoses anyway, they will fail at some point guaranteed.
And also check the brake servo hoses by the green nipple that comes off the left side of the inlet manifold. Mine was split the other day and i was loosing about the same amount of boost as your seeing.

Right guys and gals, i have bypassed the N249 checked the engine bay for broken pipes. I "Think" i found one so replaced that as well.
Here are my logs from tonight, pretty much the same i think.

seeing your log i don't think you've got a boost leak and i agree with this part of martyn post :
Martyn said:
if you still have the k03 i would say the requested boost is really too high and that's why the n75 duty cycle is maxed out, for me it seems the ecu is trying to achieved a boost that can't be done by a k03.
is this stage 1 or stage 2 ?
do you have a sps3 or do you know which settings you have, the requested seems really high to me, i have found an old log from mine in hb8 and it was like that :

I thought it was requesting too much for a k03 2320 @ 4,640 rpm
The k04 on my LCR just about manages that!

Tim, get you local Revo dealer to check what setting it's on and then knock it down a notch or maybe 2. Running the turbo with 99% WG duty means that the its is working flat out, running a turbo flat out isnt exactly a good idea if you want it to last.
