std boost pressure

[dstv]

Hi guys

Just a quick question regarding boost pressure. I had my golf remapped and at the moment im boosting 0.5 bar = just above 7psi. I read on the forum that it should be around 14.5psi / 1bar of boost. I have a stage 1 remap so why cant I get the high boost..What should I be looking for if I have issues..
I replaced the dv to a 007p with the correct spring for the stage 1 remap.

Thanks

Who mapped it for you and what engine code do you have?

[cullygti]

pcv sytem in order those figures you said are correct for a stage 1 on any engine code and should be yellow spring for a mapped car

 mk4 1.8t agu With the yellow spring.... When u say pcv system.... How would I know if it in order???

[cullygti]

if it aint it will be split leaking etc making you lose boost time to upgrade to catch can

Who remapped it is the bigger question.

R -tech did the remap....but excuse my stupid question....but when they remap the car, that effects the ECU so how will this increase the boost? Should I get a test done for a leak in my system? and if yes..how do I go about doing that

8psi standard and 11psi on 180bhp mk4.

if your pvc is leaking it will be oily. Look for oily boost pipes/ leak.

Because it is the Ecu (the brain) that controls everything I.e allows the engine to
Run At a certain boost pressure

As people have said check all hoses under the bay for any leaks, best wait is to just replace with silicone including vacuume hoses and then it's all sorte and also delete the PVC system and install a catch cahowlers are how to guides online)

Then try switching the maf and n75 (try do it with someone you know with a Golf 1.8t which is working properly rather then spending money on new parts which may not fix the problem. An of that doesn't work you could try buy a forge actuator

Thats all a good place to start
