I doubt any problems, but Cal may look at the system at inspection???

The general purpose is to aid the cat to get up to temp.
I don't use the pump [ BB in line], but I do drive the first few miles in 3rd gear range... one, to get cat up, and two, to get into closed loop asap.
because I do this by habit, I also BBed the shift delay as I accomplish the same w/gear selection..[and cuz I don't like their delay set-up]
