Turbos tend to be more sensitive to weather changes since barometric pressure, humidity and the resulting changes in A/F can affect spoolup, and that effects the way the chassis is loaded as well. The Pro-5.0 guys run 100mm turbos and run well into the 6's and are pretty consistent, but not as consistent as say a belt driven blower car, since peak impeller rpm is dictated by pulley ratios, not exhaust temperature and gas flow. You need to have one of those personal weather stations and know how to use it to tune and set up the chassis. If you run in the 12's or slower, it's not going to be as finicky. You can run them in bracket racing, but it can take alot more work and know how, which has a level of satisfaction in itself....knowing you need a brain to be competitive. Not just mash the gas and go.
