yeah i think u r still on the rich side
anyway i was told by more experience racer's here that the evo sti does not require heavy brekin in process like most engines. some only after 2-3 tanks and then they start to fine tuning.
i also was told some latest engine products that no longer requires breakin. unbelievable, believe it.
i also own an evo 4 sti. just being safe
what i did for break in was 2 tanks on the box and 3 tanks on the track for break in. after that i tuned it to race conditions. during the process i gradually closed the main needle bit by bit. now it already went through 3 races and still going strong
