Now the 4" induction upgrade complete, went to ECPT (Tuggerah, NSW) last week, put it on rollers and had tune 08 CRD.
Have been progressively doing build up(last 15months). Stock eng except:
NADS
Remap
Procharge stage 3 h/f turbo
Tillix/needle (Max B 26psi)/13.5"Hg VNT actuator
Jonny Tig cooler
Ben Lipscombe - 9" K&N Pod / 4" thru airbox (3" to turbo)
4" fwd facing snorkel w/safari air ram
3" exhaust turbo back w/ muffler and cat
Had a couple of tunes along the way, latest being after install of JT cooler and 4" induction.
Running 33" m/t
Leaned it off from AFR19:1 back to 20:1, could have put more fuel but this has provided a good reliable result: 136rwkw and 512 N-m/4th gear.
Dyno results attached, my CRD "Blue Trace" / the "Red Trace" is for comparison purposes of a stock 2010 CRD on 33s and 3" exhaust on the same dyno.
Achieving 20psi Boost @ 1900-2000 rpm, max B 26psi @ 2200rpm (good to drive).
With the upgrade to JT cooler and 4" induction gave me an extra 70 N-m. From 378 to 450N-m and with the tune last week now producing 512 N-m. The trip back home from Tuggerah, NSW via Sydney (400km). fuel usage 12.5l/100km.
Old post but...Jesus John thats pretty impressive. Gotta be happy with that.

She rolls pretty well. Have had some further improvement, especially low down torque, resulting from adjustment to the VNT actuator rod length (reduced "Hg) to hold
the vanes closed longer so the turbine spins up quicker. Was laggy 4&5th low down due to larger exhaust wheel(Procharge H/F turbo).
Currently achieving boost 25 psi all gears around 1950 rpm (all out by 2100rpm_26-27psi). Also been trialing max spool (using Tillix only with needle disconnected) and a throttle control unit that has removed a lot of throttle lag (caused by drive by wire_CRD), linear spool. Different dyno (reads a bit lower than previous), but note low down torque improvement_ from 250 to 300 N-m(max nom 530N-m). Always adjusting actuator rod but so close now and will soon go back on rollers, may be a little more fuel early on. Looking at FMIC (still a 600x300mm T&F).
