After seeing various dyno readings with de-cats, exhaust , piggyback etc.. I was a little concerned on the AFR readings on the runs . Some where hitting 14:1 and some 15:1 , I know I keep banging about this , but knowledge shared in this area is always a good contribution to the forum, before someone's engine goes bang ! . An ideal reading is between 11.5:1 to 12.5:1 on full boost .
I know the boost controller will accommodate for boost correction , but will it compensate in contribution with the piggyback which is fooling the boost settings already ?
