Fixing a Flat Spot in the Rev Range

As per Poache's reply 

It will give you specified VS actual values so you will see if you are losing boost 

Wish you were closer to me 

What sections in VCDs can i use to measure / check if boost and air is correct. Do you have a guide or instruction i could follow

Go into Engine then measuring blocks and scroll through

And do what with the values?...what should they be?

Mine does the same, I have checked and no faults stored.

I am 99% that its the bluefin map

The measuring blocks give you specified (what the ECU requests) vs ACTUAL which is what the car produces

The numbers need to match. Do a full throttle run in 3rd gear to the redline. In the lower rpms the numbers wont match as the turbo spools up but once the turbo is spooled then the numbers will follow each other to the red line. If the actual tails off vs the specified then you got a problem

DV generally doesnt flag as a fault unless its kaput

Well i have bought a New Rev G DV, Should get it fitted this weekend.

But im starting to think it may be caused my Spark Plugs or Coils. Hard to explain how it feels, just doesnt feel strong as normal, like its not pulling hard.

Well VCDS can be used to detect a misfire if it isn't stored in the fault memory already.

Have you checked for any stored faults yet?

Yeah no fault codes in regards to engine when doing a general scan. Just a mirror fault - which i know about, and a SatNav one which i know about.

Do you have to do a certain scan in a certain section?

[Poached]

Not for an auto scan.

Did you ever have a dyno run when the map was put on?

I recommend a dyno run to log some key blocks to determine if there is a problem.

No Dyno as it was Bluefin. The problem has just arrived in the last few days. Its been running sweet for 2 months.

There is no real decent tuner with a RR near me, nearest one is Awesome or Stallers and they have a 2 week waiting list.

It just feels a bit hesitant through out the rev range - Im sure its gonna be the DV....if that doesnt fix it then dyno may be needed.
