We run one in a 2188. Just went to the hardware store and got a quality 30 psi guage. You will also need the smallest copper tubing they sell, compression fittings, and an 1_8" NPT male pipe fitting. An easy way to hook it up is in place of the starting fluid injector. Technically it will not work as well in a 2188 because the wastegate will max out in boost pressure before the rack maxes out in fuel. However, we find it very useful and use it constantly. It reacts instantly to increases in HP output, as long as you are not already over the wastegate pressure setting.
