So my evo is tuned for e-85 at 28.5 Lbs of boost, the other day when i went to go buy e-85 i boosted and spiked to 30.7 lb of boost and my a/f's Dipped to about 9.7 why? i have a dejon tool dual mbc's. Is 9.7 to lean for e-85?

 

9.7 is rich

WOW for real then i had my numbers backwards haha so i shouldnt be worried?

 

Should i be worried that i have to call my tuner or i can leave it like that? i hit 14.7-15 while cruising or idle
