Very easy to tune. I didn't do my install because it was a bit over my head and I don't have the facilities to do so. When I first picked it up I was scared to death, had no idea about fuel mapping and EFI's as I have always been on a N/A sled. Upon installing boondockers starting numbers I went for my first ride. The starting numbers were REALLY REALLY close so dont feel like you are gonna change everything. Once I had a general understanding of EGT's, thier relationship to fuel mapping and how to read my boondocker stats.....it really comes together. Just take your time and ask as many questions as you need to. There are many people on this forum willing to help you.
I now have three days on my sled this season (120 miles) and feel like I have it tuned in pretty close. Gonna take you a full day of checking stats, resetting, running and then do it all over. It really helped for me to go up and write down everything I was Running (psi, egts, temp). Make yourself a chart and you will save yourself a headache.
Remeber....ASK AS MANY QUESTIONS AS YOU NEED TO! At one point the guys giving you answers and feedback were asking to. Nobody comes out the womb with inherient turbo knowlege. GL
