or your turbos screwed.

Cheers John :(

It's hitting/exceeding requested at 4,000 so hopefully it's not that, but it's dead peaky, and it's no where near requested up to 4k, and then from 4.5k onwards.

As i said log 115 and 118, along with a separate log of 003 and 032.
118 will tell you what the n75 is doing, with 003 telling you airflow and timing, and 032 telling you fueling.

Could be a screwey n75, maf, map, or a boost leak, vacuum leak, dodgy dv, amongst many others.
Post the logs. I'll take a look. It doesn't sound like a turbo problem.

No faults, no whoosh (not that I can hear anyway, mind you - I didn't know about the other one), I keep checking connections, can't see any sprayed oil...

Yeah - I think so anyway, leak from around the MAP sensor. Might not have been it, or there may be another I suppose? Are you saying it looks like a boost leak?

You've got a huge boost leak. Your n75 is at 100% all the time.
I meant block 31 not 32, but it looks like the block 32 suggests that the maf is seeing more air than is going into the engine, so the car is cutting back fuel by 22% to maintain the correct fueling.
Your turbo is moving the air in, and maf values look ok, but the air isn't getting to the engine. BOOST LEAK!!

Check that none of your hoses have split near the jubilee clips. Turbo outlet is usualy the first to go. Don't forget to check the pressure hose to the dv and n75 from the turbo outlet pipe.

Thanks :redface:

You'd think I'd be able to tell, but I can't hear anything.

I've just tried to work out when the last time I serviced my DV was :whistle:

Stage 2 REVO, certainly feel it now, comes in later than stage 1 did, certainly helps having the the FMIC for the temps though.

I need to play with my settings and do some more logs, been full of lurgie though just recently so not felt like going out :(
