hell I watched an SAFC get tuned on a celica GTS, sucker gained 12whp. twas freaking nuts.
Sadly the ecu in the 7th gen celicas is too smart for the safc and it eventually overrides the settings, so everytime you wanna take advantage of it you have to reset your ecu. I saw online, a guy attempted to tune his turbo GT with an s-afc and after like 3 pulls the corrections would vanish, the ecu would learn and say no no. If you want to tune a 7th gen right you have to at least step up to an e-manage, but the best is a Apexi PFC.
