Hi All,

I'm a big DIY'er and I built my own GT28R turbo kit for my 2004 B5.5 VW Passat 4 Motion 5 Speed.  I've built a few toys including a drag bike, RX7 turbo and an airplane (still under construction).  I can't bring myself to pay someone else to tune my car, so here I am to learn.

My tuning knowledge expands into knowing about AFR/EGT/Timing retard and what I WANT those figures to ideally look like - but I have never dabbled in the actual tuning portion.  So I guess I know what I want, just not how to get there.

I'm looking to run my car around 300 CHP or about 19-21 PSI on the present setup.  I'm not trying to max out the turbo or really really push my stock bottom end.  Looking forward to lots of reading and learning.  My setup is as follows:

GT28R
FMIC
550cc EV14 injectors
3" MAF housing

No, it just means you have to either:

A: Define it yourself
B: Find someone you can pay to define it for you.

If you choose A, I'll help with any map locations you can't find on your own. If you choose B, I can steer you towards those that won't do you wrong.

I personally hope you choose A, but defining a file from scratch is one of the more tedious things you'll do.

Welcome, and good luck.

The tunerpro site has a lot of good whitepapers and stuff on this topic.

I will get started this weekend, thanks for the above as a launching point.
