Garrett T25 Boost Pressures
Garrett T25 Boost Pressures
Surely a Garrett 25 turbo should be able to produce quite a bit more boost!
Do you guys have any input?

03-02-2013, 06:43 PM #1I have fit my new hybrid MTDI pump to my OM602 DE2.9LA motor and after getting the advance figured out (PITA), I am now working on the fuel delivery. I've "turned up the screw" and now the motor is slightly "peppier" than when it was electronic (and with the same or slightly higher EGT's)... However, I can't seem to get the boost to go any higher than 9 PSI (.62 bar).

And still no more than 9 lbs.
I'm running 3" exhaust tubing.

And still no more than 9 lbs.

I am getting 28 psi on standard fueling without ALDA if I hold accelerator to the floor for to long from standing start. Waste gate control is disabled. While driving no more than 18 psi while flooring.
