Hi all, hope I've posted in the right place...
I have a 2002 ALH (on 180,000 miles) and recently acquired a re-mapped ECU. It claims 130 BHP from this engine! I'm a little skeptical about the turbo life expectancy so I thought I'd find out what it does with the turbo. So, I've logged group 11 in VCDS (engine RPM, boost requested, boost actual) and have produced graphs like the following:
X-axis is TIME, in seconds
This was low gear full acceleration. The boost spikes at up to 2600 mbar absolute.
I then tried a 4th gear, 36 to 60 mph WOT test and got the following (see the square orange curve from 1077 to 1085 seconds ish):
The x-axis is TIME, in seconds
This shows the boost spiking at 2200 mbar but then dropping down to a sustained 1900 mbar.
My question is: is this likely to pop the turbo? Thanks in advance!
