i never updated my sig. i actually have a powrtuner now.

Ya this is all stuff at WOT im talking about. at cruising my LTFTs read in the 15.6 to 16.4 range till i go WOT. The guy that tuned it said thats normal with e85. Before it was tuned they never touched 16.4 or even close. I know there is no vac leaks as i have sprayed everywhere with brake cleaner with no idle changes. From what i understand 16.4 usually means vac leaks.
