HELP! Still not enough boost

[Dougy]

If you haven't read my other post then just a quick update

Fitted my boost gauge and was getting 10psi
Tried another gauge and was getting same reading

So I asked on here and someone asked for my 3rd and 4th gear readings which are below these were done before fitting the N75 Valve:

3rd Gear

4th Gear

Then looking at the figures someone said it looks like N75 valve and so went out and spent £70 on a nice new one for it to make no difference.

Its not the MAF as a replaced that a few months back

There is no fault codes on vag-com apart from outside temp sensor which I doubt will make the boost low

I have the following mods:
Stage 1 remap
Jetex Filter
007P DV
Cat back exhaust


If anyone can help it would be appreciated i'm loosing my rag with this car now and i just wanna

Thanks

Could you get a log of 118?

Possible boost leak but then again the map doesnt request much at all so it could have been mapped pretty conservatively making it a mild map, if thats the case im sure will at p-torque could easily crank it up for you.

what gear to log 118. I emailed will who suggested n75 valve which i did and still nothing so waiting for a reply from him. Thanks for replying

Always best to log in 4th gear if safe enough to do so.

Make sure the N75 is plumbed in the correct way around also.

Anyone got a picture of N75 valve so i can check its right way, I just put it back on the way it came off i think

 

[Dougy]

Or infact a picture of their engine bay so can check everything plugged in right

 

[Dougy]

Somebody has told me this could be the actuator and that it can be bypassed to check it

Is this safe enough to do aslong as I don't go mad on the pedal
