Penner showed a gain of 25 or 26 max rwhp to about 175. If your mechanic has a professional TuneECU license, he has the hardware and knows how to load the map. If not, you have to buy the Android device, the OBDLink LX and the app. It takes at least a day after you purchase the app on TuneECU.fr to getting the app registered so you can use it. All the instructions he would need are on that web site.
