new boost gauge

after fitting my new boost gauge ....... bpu now reads around 1.1 bar is this correct?? how do i get 1.2 bar???????

Do you have a restrictor ring in the exhaust?

yer a 1.2 bar restrictor ring

Ok, well take it out file the diameter a little bit larger OR buy an electronic boost controller and raise the boost that way

its about 1 - 1.1 from like 50 mph - 80/90 mph

Yep... so take the restrictor ring out, file the hole out so its a bigger diameter which will cause less back pressure and the turbos will boost more. Just file it a little bit at a time or you'll end up hitting more than 1.2bar. Trial and error mate

Don't forget though, in hotter weather you'll boost less than when its cold. so if its boosting at 1.1bar when the outside temp is warm, it'll definately hit 1.2 at night time when its colder

A better way to achieve 1.2bar would be to leave the restrictor ring as it is and fit an electronic boost controller to raise the boost, but this method is a little more expensive.

are boost controllers easy to fit?? how much should i file at a time??

I've never fitted a boost controller so can't tell you. I have just bought one though and most come with good english instructions

Just file a tiny bit at a time on the restrictor ring, like I said its trial and error on this one. IIRC the diameter should be 52mm to achieve 1.2bar, but every car will be slightly different depending on how well the turbos work etc etc

Boostcontrollers are easy to fit.

maybe ill try flooring it tonight see how the reading goes in cold

when i baught my new car a couple of weeks ago it was boosting to 1 bar. wouldnt go any further.

Today ive been to a RR day and on the way there and on the dyno it was boosting 1.3. Mostly because its feckin freezin today i guess

Measure it on a cold day in 5th or 6th gear (assuming a 6 speed) and see what it reads you don't want it running too much boost !
