I fitted some defi gagues to the car at the week end and went for a run out to test them and noticed that the boost gauge would climb as high as 1.8 bar possibly more.
I have been driving the car for 5 months now with no problems but now I'm worried something is wrong somewhere?

Car is my99 uk turbo with vf35, fmic, 440, walbro and 3 in down pipe.
Has had an ecutek at some point previous to be buying the car.
The only thing I've changed since then is a 3" blitz Nur spec.

Could this be the problem? I no it will need remapping just waiting on a few other mods first.

Any ideas ?

 

new engine in the making if you carry on, 1.8 bar and not mapped for it is a killer.

 

I know but what could cause it to do that.

 

have you played with the silicone hoses ?

 

Only cut a joined in to a vacuum pipe that runs to the inlet and boost control solinied to fit the boost gauge.
I have seen other people have t pieced in there before.

 

have you removed the restrictor pill in that pipe by accident ?

 

No, the restrictor pil is located between the acturator and the turbo on my car

 

has it only started to do this since you installed the gauge ?

 

No I don't think so.
It still drives the same, I was unable to monitor boost levels bofore that's why I fitted the gauges.

 

might be worth getting it on a rolling road for a health check.

 

What eco and map is it running currently? If it has the mods you mentioned and a standard map or eco then it is definitely over boosting!

 

It has already been said in the 1st post that it's been mapped using ecutek.
I'm surprised it's not hitting fuel cut over 1.75bar?
Unless it has an updated map sensor. Afaik the standard map sensor should be rated to 2.75bar which would be 1.75 max.
I very much doubt that any mapper would set the boost so high on a standard uk2000.
Are you sure the boost gauge is reading correctly?
I would stay off boost until you sort this out.
Check all pipe work for splits,holes etc.

 

I interpreted that as it had an ecutek at some stage but might have been removed. Maybe I picked that up wrong.
