MAF Sensor Boost Adapter?

[akingcool]

So I recently bought a Stepper Boost Gauge for my A3 1.8TFSI and fitting isn't as simple as I first thought due to the electronic dump valve.

Now from my research I can only see two options:
MAF Sensor Adapter: http://www.forgemotorsport.co.uk/Boost_Gauge_Adaptor--product--1062.html
Replacement Valve: http://www.forgemotorsport.co.uk/Re...FSi_Engines--product--815.html#specifications

Now I would obviously prefer the cheaper option but correct me if I am wrong, but how can you measure the boost pressure before the turbo?

And I don't really need the whole replacement valve kit as at most I will be doing a stage 1 remap on my car. The only real part I seem to need from the kit is this part:

The Vacuum tap for the intake manifold... and instead of the pipe going to the mechanical dump valve, I could have it going to my boost gauge sensor.

Thoughts?

just buy a boost tap

you mean something like the photobucket photo?

yes

plenty of places sell them between 15 and 40 quid.
easy to fit work as they should etc.

I have seen this: http://www.forgemotorsport.co.uk/Boost_gauge_fitting_kit--product--915.html#specifications

but it says only for the 2.0tfsi engine... but it looks like to me the vacuum hose adapter into the intake manifold from the £200 replacement valve kit (which fits both the 2.0tfsi and 1.8tfsi.

 

[hades-]

they fit both 18 and 2.0

no idea why they never list the 18

so just to clarify I would be better off with this: http://www.forgemotorsport.co.uk/Boost_Gauge_Fitting_Kit_for_20_Litre_FSiT--product--915.html over the MAF sensor adapter?
