Modification info for other newbies!

[Wilburnator]

Hey guys, I just wanted to post some updates re the mods on my CRD in case there are other newbies like me that aren't sure what to do next.

It's seemed to me that boost fluctuation and high egt's were the biggest concerns after purchasing my 08' 3 litre, so most data is based on that!

Bear in mind this is just notes I took as I did the mods!

Here goes, (redarc boost/egt gauge and eds scan tool)

Unmodified - 14 psi max but all over the place, and very slow ramp rate. Very high egt's hitting around 550-600 on steady hills with no load!

Maf sensor clean - higher maf readings at idle and smoother running at low rpm, slightly lower egt's

Dawes/needle install - after tweaking boost about 18psi, and increased spool rate, much more power down low, better acceleration, egt's were around 350-400 on the flat at 80kms (daily work run) then played with the needle valve and got it to spoil faster, Egt maxed at 350, but was still around 550 towing on hot day. (Did hit limp mode at 18psi, so have dropped it to 16psi)

Egr block - maf readings at idle doubled, higher in general. Egt's went way down (not sure why??) sits around 250-300 at 80kmh now?

3" exhaust - higher maf readings again, significantly lower egt's (60-80km 200-250ish, not really sure as gauge doesn't go that low...) up a reasonably steep hill at 80kmh went as high as 350.

Next up, intercooler...

Hope this info is helpful to someone in the same position I was...
