Car is running. I let Sergio do the actual break in drive since he built the motor and has his way of breaking it in. Only issue we couldn't fix was what he described as the engine not knowing what to do during half ass accel or decel. We think it's related to my BOV being uncirculated and the ECU trying to learn the new setup. I'll give it a couple days and if the ECU still doesn't pick it up, I'll figure out a way to recirculate the BOV, which by the way is a Synapse synchronic. He said the UEGO was saying the car was jumping from lean to rich and vise versa. I'll take a note of AFR readings today. What's left for break in is filter change today, another day of driving, making the engine see a lot of vacuum, lots of engine braking, and the day after will be the head retorque, at which point I will change the plugs as well. Once I get to 100 miles including today's driving, I will change the oil and filter again as well as my transmission filter.
