Well today we fixed the mafold leak and well no more leak. But it still does not creat anymore then 12psi. Drives great but high egts. I'm going to check my pump timing but what else do you guys think I should check?

Egts could go way higher then 1400. And i think there is tons of fuel I think. Any way I can tell?

Is boost flattening out? If so you need to put more preload on the actuator as it is opening too soon.
To lower EGT you need more boost

Right now I have the actuator blocked off. I just disconeccted the vacume line. Makes a bit more boost but only 2-3 psi more. Today it seems like I have a boost leak so I'm going to look into that. It is running really rough at idle so I also need to look into that.

How is timing set on the pump?

Not sure because I did the can swap back to stock. And I have not had a chance to check yet. But I went to my local vw expert and we believe I have a bent valve. Any chance that would affect boost?

A bent valve will not be good for anything

Haha well that's a good way to put it. I'm checking pump timing and compression tonight and hopefully that will give me a result even if it is good or bad.

i believe 400 is the limit, below that and ur either worn out or have some type of issue (hg, burnt/bent valve, cracked head, toasted rings)

I'm not really sure my local Volkswagen guy said that is not to bad. We did pump timing and that fixed the running rough problem but still low boost and high egts. I even turned the fuel up and no change. Next is to smoke the intercooler and piping

Ours is running great. ~26-27 psi, and EGT stays below 1200F with a third-gear pull. We get quite a bit of wheelspin in second. It's a lot of fun, and we still have a lot of room for future upgrades.
