at a guess, its only recorded 199g/sec vs his sig saying 218g/sec

Whats requested vs actual boost look like (block 115) and how does the timing correction factors look (cant remember the block)

Also log the fuelling on whatever channel thats on and see what its doing, and have a look at your fuel trims too.
 
Here is some more, power taken from maf which is 4 month old from tps.

cheers

Out of interest do you know what Revo timing & Boost setting you are on?
 
I think its on standard settings but unsure, what they are on this one

Theres a bit of a hole in requested vs actual boost around 5-6krpm?

N75 is pretty much wide open trying to sort it too...

Turbo tired maybe?
 
silly question, but does colder air equate to high g/s?

was the time that you logged g/s a while back on a cold day, and recently logged on a much warmer day?
 
My car suffers from severe flat spots under hard acceleration.. I assume logging is a good method of identifying any issues with the engine..

What software is required to execute a log?

I've got vcds cable with lite installed on laptop. Can I take logs with that?

Sorry I can't help you with your problem epox
