anything i may be missing

[chivasreal]

I have a 2001 Audi S4 and the timing belt with every thing else has been done. I never really drive it hard just when passing or merging into traffic.I need to take care of my very leaking auxiliary pump. Im also looking to replace my valve cover and intake manifold with powder coated Germanys flag colors. Also the car is jerking when I'm trying to build boost which I'm hoping i find the boost leaking while doing this job.
I have both valve covers and gaskets
intake and spacers
auxiliary water pump with both hoses

So couple of question.Would it be best to also replace the pcv spider hose. Ive seen some people doing there on design just want to get some ideas on whats best out there. am i missing anything else while doing this job and will i need any specials tools or small/big vacuum hose to replace? Also where is best the place to buy factory like hose clamps

thanks

You should have just done an aux pump delete instead of getting a new one (search will show you how).

Jerking car - log and see if there are codes.

Clamps - ABA Swedish clamps are easier than OEM Oetiker and hold tight.

Im also thinking about doing some injectors but not sure if i should go with bigger. I'm only running ko3s(exhaust and other upgrades are done just not turbos). or just new stock ones

Injectors won't matter unless you plan on running E85, then you would also need a fuel pump.

Stock injectors are fine for any pump gas stage 2+ tune.

Hesitation could be misfires, scan.
