  1. You could try pressure testing the piping between the turbo outlet and the throttle body . You can diy a test kit with some PVC pipe end caps and installing a tyre valve in one - then hook up a compressor and see if it holds pressure. I found I had a couple of spots that looked and felt ok but actually leaked slightly. Hopefully the tuner has already tested this properly and not just had a quick glance. If you disconnect the wastegate line you should boost to the moon. Maybe try this first (but be ready to jump off the throttle before you go sky high) if you make heaps of boost this way you know you have some sort of wastegate or wastegate control problem but no boost leaks. I spent a lot of time last year chasing a low boost problem. Turned out I had a piping leak AND a failed wastegate which made testing and tracing a bit confusing. Edit: just took a pic of my boost leaks tester so I'm making more sense!

  2. Just upgraded the fuel system. Plazmaman twin feed rail. Twin -8 feeds, single -6 return through Turbosmart FPR2000. Bosch 1500cc injectors. Already had plazmaman surge/twin pump setup, with flex fuel sensor plumbed in somewhere in between. Seems to run flawlessly. The 540kw the car saw on 20psi had the 1000cc injectors reaching their limit, so I removed that future limitation. Also got 1400hp axles to install. The repco ones started clicking after last track day... Lastly, got a 3d printed dash insert to suit IC7. Might install that one down the track. Slowly slowly progress continues.

  3. 1. I wouldn't bother using one of those actuators... they're cheap and nasty (as you found out) and hard to setup the preload properly. 2. the 1.15 rear housing needs to go into the bin... another cheap and nasty item. Just get a replacement garrett 1.06 rear-housing.
