Post by: EuanGtTdi on 12 May 2010, 14:58
Just wondering if soemone could tell me what psi my boost gauge should read under full load on my gttdi 115?

as it hits 25psi and drops off a wee bit?

standard or mapped??

25PSI peak sounds about right - you'll overboost then settle down

My 130 hits 27PSI then settles at 23PSI with the R-Tech spec 2 map

it won't make much more than that due to the size of the turbo

Not entirely sure what standard PSI they run at tbh; think the 130 is 23 to 19  :undecided:

What does it drop off to?  And does it keep dropping?

The fact that it holds it means everythings working as it should!

Wish mine did that :(

I peak at 26psi hold 23psi then tail off at 19psi with no visible signs of a boost leak. :(

You do have the better turbo.
