I have a OTC Monitor Elite, they make several other modles, and you can add any software, for any model made. Also have all the cord sets. If you have the need, they can provide you with printers, break-out boxs, ect. Just limitid by your budget. They are fun, you can sit in your driveway and read bar pressure, coolant temp, boost pressure, tps position, voltage output, ect, ect. The monitor elite starts at arround 1300. 00, list, and options go up from there. You can however find it abit cheaper on the web. What ever you decide, make shure it's a well know company, and they will be there several years down the road, when you might want to up-grade, or obtain new model up-dates.
