10k$ is definitely a no go for such power gains. we'll see how it rolls out. The DPF delete might happens anyway if it get troublesome, it is most likely cheaper to delete than OEM fix. As there doesn't seems to get a significant power gain, but definitely a big change in emissions I'll wait. I do a lot of short city driving...
Turbo upgrade would happen if the turbo fails AND I cannot get it fix under warranty. we'll see!
As for the tune price, Malone only charges the tune price difference +100$ for re-flash when changing tune. I already paid 650$ for stage 2, stage 3 is 800$ so I have to pay 150+100$ for the new tune. If I do the DPF delete, it is another 250$ on top. If I only do the DPF delete, it is 250$ + 100$.
I got a quote for 1100$ CAD for springs with installation (springs are 500$ CAD alone), I find it a bit steep. Considering the struts have to be remove to install the springs, the truck/struts age and significant amount of labor involve, I want to do it properly and do the shocks at the same time as the springs. I expect the suspension bill to be a bit more, most likely top plates and some linkages/bushing will be required too. Doing only the springs now, and upgrade the shocks in a year or so doesn't make sense financially. The plan is to keep the car 5-8 years, so I guess I can get most of the life out of the B6 struts. All in all, this should be just over 3k$ CAD for struts, springs and spacers.
springs, 450$ (275$ USD for ECS or other)
struts: 1600$ (1581$ from rockauto, if no duties)
spacers & bolts:400$ (225$ USD + shipping)
duties, taxes, alignement, surprises...
