i'd get his tune depending on price, at least until my warranty is up. I'm not doing much engine mods because once I "tire" of driving the car im going to swap a stage 2 LNF into it, (or wait to see what the 1.4t is tunable to).. but @ 300 reliable hp will keep the car interesting.
I'm not sure how long it will take me to tire of it, i've really only driven 300 miles or so since june? gave it its first tank of gas since may in mid august.. only real driving i have done is "parts testing" its been up on jacks for R&D most of the summer. but tomorrow i start driving the kids to school..
