Ok i have just finished building my motor but its not running yet and i was reading about breaking in engines and i read that I should get tuned right away before doing doing anything else with my engine. It said that the motor could get messed up within the first few minutes because the fuel mixture is not good. My steup is a B18c1 with P30 pistons, CTR cams, ITR valve springs, Skunk2 I/M and JDM ITR header. Everything else is stock. I have a stock gsr ecu and im wondering if it is safe to drive a 11.6 CR engine on a ECU made for 10 flat?
