I've got a friend who is looking for a 5000 CSTQ. He'd like to know what would commonly go wrong so he'll have some things to look out for. Any suggestions? Also, where does boost normally kick in? What should the meter read at full boost (one is reading approx 1.3 bar)? Thanks... - Josh Pinkert - flush@radix.net - '98 A4Q 2.8
