I have a 90 supra. with a greddy front mount and ct26 57trim turbo running 12psi of boost. my egt's hang around 1500-1600 untill you get around 150mph then the climb in the 1700 range. those are in F obviously but just in case. let me know that you guys think? AFR's stay aroung 11.5 to 12.5 so just wondering for safety reasons. thanks
