I think most of you didnt realized that when the stock Fit on partial throttle, the AFR is at 14~15 range so with the mods, there's nothing to worry about ruining the engine unless detonation.

does the af ratio in partial throttle differ from the af ratio in WOT?
why is 14 considered lean? I always thought that running lean is above 14.7. please enlighten me.
"the test pipe alone will lean it down a bit to give it some more power." - i also thought that running lean is for better fuel economy and not power.
please forgive me for my noob questions. I'm new to this topic. my mods are: T1R intake, 5zigen headers, 2inch header back exhaust w/ resonator and spoon axle back. No cat converter.
Oh and by the way, Jason was very helpful and accommodating during my purchase of the intake. he painstakingly answered all my questions. excellent service guys.
Thanks
