Decoke / new exhaust / ECU remap
Finally got a chance to go back to MRT to have the XB kit fitted over the last fortnight. They did 75k service & inlet manifold clean first over a couple of days, then yesterday fitted new 3" ACMS + stainless rear muffler. This is the Beaudesert Exhausts kit, which is mandrel bent and uses original mounting points, also keeps the same clearance off the bashplates & body. The weld quality & alignment is spot on, certainly looks a quality product. This also necessitated another tweak of the ECU to allow it to use better engine breathing. A minor issue was the Redarc EGT probe didn't quite work with existing bung so they had to drill an extra hole for the compression fitting.
It is a significant difference again from the first upgrade, cleaning the manifold and inlet ports has given the Paj a real boost. MRT claim an extra 35kw & 40% more torque with the XB kit (ECU remap + exhaust), without having gone down the dyno route, I would have to say seat of pants impression would definitely agree with this. The vehicle just feels a lot more responsive to throttle input and the turbo spools up to full boost a LOT faster. It was previously blowing smoke off the line with the just the remap, this has completely cleared up with the new tune.
As Apsilon mentioned in his build thread, it is not explosive acceleration, just goes hard in all situations and you find yourself travelling faster than previously. There are a couple of places where I turn right across busy traffic on the way home, previously I had to wait for a large gap to get through, last night it felt almost effortless to get around in front of the oncoming traffic.
Really happy overall with the work undertaken by MRT, not cheap but definitely worth it in my books.
Cheers,
Stephen

I had been considering an aux. tank for a while for some longer trips coming up over the next few years so bit the bullet and asked Eddie & Chris at Artarmon Automotive do the job. There has been a bit of a rush on these, Eddie indicated this was the second they had fitted that week.
