I have been running the tune for 3days now and like you all the improvments are verry noticable, the engine is running much smoother and the acceleration and power delivery comes in steady, also the starting issue is no more so far and i hope it stays that way.
I did however find some small leek at the up pipe going to the turbo and that was fixed.
I have not seen the temp Issue come again as i described previously.
Overall verry happy with the changes this tune made.

Has anyone considered a wastgate controlloer? Wouldnt they help stablize the compressor even more and stop the possibility of surging?

Regarding heat wraps, i wraped my exhaust prior to instalation with Titanium wrap, i did not do that expecting any performance gains but only to keep engin bay temperatures down.
Im now also looking for solution to relocate the trans cooler, the way its set up now is ok with the cool temp we have but once we move into summer and we start to see temp of high 40'sC and high humidity my radiator will struggle with all that is fitted infront of it.
I welcom any ideas in this regard.
