I just got my truck tuned and when i go WOT the AFR goes to 11.5 as commanded, but then works it's way back to 14.7 while i'm still in boost. Shouldn't i stay at ~11.5 the entire time i'm in boost? why would by AFR start creeping back to stoich? it takes about 2-3 seconds for it to get back to 14.7.
do i need to adjust any tables?
thanks!
