After fitting the newly built tubs and replaced engine i have finnally got to stage where im checking everything. I turn here over she starts up perfect on the buttom im checking iol pressure that sits nice and gose up with a blip of the throttle then im looking at the boost gadge i have a uk tt. The gadge when running on tickover reads -14 and as soon as o blip the throttle shes up to o in the middle but shouldnt she go further is she in safty mode or something i cant run her down the road because its on ramps there is one other issue about breathing but ill look at that tomorow. if she is on safty how do you get her off?

cheers.

You won't get positive boost pressure unless you take it out. Sounds like the gauge is doing as it should.

 

Safety boost is about 7 PSi iirc.

like si said

 

as the engine is under no load it is not producing enough exhaust gas to turn the turbo fast enough to create boost.

must be a healthy motor pulling that vacume on idle

well ive replaced the air filter with a k and n one which has a diameter of 9 inch at the base where the intake is this then runs down 9 inchs to 4 inch at the bottom and it barks like a hudge dog, maybe that might help.

Exactly what these guys have said.....

 

.....take the car out on the road and see what results it produces. But do go easy on the loud pedal with those new tubbys until all is warmed up and (properly) ready to go!

thats going have to wait she still not legal and ive yet to do the brakes next.

The ecu is probably needing to "learn" about your new airfilter and settings. As mentioned a good drive should sort it all out.
