tdi 110 boost figures

[bluetoledo]

right i fitted a boost gauge today and i have taken it out for a drive to see what sort of psi it was creating.

at 2000rpm at 45 mph in 4th with foot to the floor its only creating 10psi??

when the turbo does kick in around 3000rpm its spiking at around 19-20psi and then constant is around 15-16 psi.

is this correct for an unmodified 110 or does it seem low??

i put my foot to the floor at the same 2000rpm at 45mph and the boost spiked at 19-20psi then dropped right down to 10psi then when it got back to around 3000rpm still in 4th it spiked back up to 19-20psi then back to constant 15-16. something isnt right but dont know if its a sticky turbo or a maf or a map problem.

any advice would be grealy recieved.

cheers people

Hi, the figures sound about right.

now you know what you're getting, if you have a guage which also measures vac tap into the control for a while, then you can check signal vs actuator movement

how do i know if it does? and how do i do that? im a bit thick when it comes to turbos and vacs.
