Sorry about the delayed reply. I went from 98.04 in October (great weather) to 105.56 in July (shit hot and humid) with that being the only change. Stock A340E. And 1/2 second faster ET in the 1/8, so it isn't all on top either.I have a Boss Jr that I bought 10 years ago still in the box. Has taken me that long to install the supporting mods, including an IPT automatic and the CT26 has been more than adequate to run 12 psi over those years.
