What is the most horsepower I can get with the EVOs stock E.C.U. ?

 

Seems there are atleast a few evo owners with Re-flash, AFCII, and bigger injectors running clost to 400whp. That is probobly really pushing the point at where the gains of going to the ems start stacking up.

 

im using the ems now but im having trouble with it bcoz my car is an EVO 7 and the ECU is for an EVO 8. if i go back to my stock e.c.u., with a TOMEI 2.2L stroker + cams and a greddy t-67 turbo how much whp will i be looking at (with 720cc injectors and s-afc 2) ?

tomei evo7 i would check HKS Kansai for 1 of their ECU's. may be expensive but it will unleash more power out your setup.
