>>I will be picking up a bently manual, and using that as a guide to help me with fuel increase, also with these mods, will I need to make sure my egt is not too high....
Not sure if that was a question or not, but YES, if you increase fuel, you definitely need to watch your EGT's. As you may know, increasing the fuel can make EGT's rise signifigantly.
>>the egt gauge may come in handy for cool down purposes
Actually, most people use them as an indicator of combustion temps while the engine is under full load to keep from melting engine components.
As with any turbo engine, you should make sure to let the engine / turbo cool after hard runs. EGT's cool pretty quickly when you get back down to idle, but that doesn't necessarily mean the turbo / manifolds have cooled off as well.
>>also thinking of mounting these gauges on the side pillar, they call it the A pillar,
Yep... I did that in my rabbit truck. I bought the Auto_meter one that's supposedly for the Jetta III and then trimmed it and shaped it with a heat gun to make it fit. Not sure if they make one for the A2's... I've got pics if you want to see them.
>>am I hurting the engine/turbo with this over fueling, ie higher than normal EGT.
Quite possibly. If I were you, I'd set the engine back to stock timing / fueling specs and get an EGT gauge as soon as you can. At the very least, I'd be VERY careful in staying in the boost for long periods of time.
Cranking up the fuel without monitoring those temps could very likely lead to dangerous temperatures / meltdowns. Right now you have no idea whether you're running 1100 degrees or 1600 degrees.
You'll have to most likely pull your exhaust, turbo and manifold to install the EGT probe (pre-turbo), so give yourself some time. There are excellent write ups here on EGT gauges and the install process.
Hope that helps. Best of luck.
