Welcome Brandon! I actually work in Lees Summit so if you want a ride in a Stage 2 GTI I can show you that it is "worth it"
Stage 1 is plenty fun as well and during the APR sale it can be had for $600 (local shop charges $200 install though)=$800 total. Again it's totally worth it to me because stock the GTI is...WEAK. I went Stage 2 the cheap way for about $1200 total (ie. saved a ton on my downpipe).
I have vagcom and will work on your car for a one time $20 fee. Just let me know what changes you want to make. If you ever want additional changes or need a diagnostic before going to the shop I will do that no charge after that one time fee.
I am leaving on vacation for a week but holler at me after that and maybe we can meet in Lees Summit. Welcome and you made a very good choice!
