Just seeing if I have this all down before I head into tuning my truck. Truck is a 2012 e38 Silverado stock 5.3 adding a turbo low boost at first 3psi then up from there. My plans are to be MAF only since the sensor is more than capable. I will be running driver side o2 sensor in crossover pipe and passenger side o2 sensor in down pipe along with afr sensor. I will scale the maf and adjust timing as needed but at first it shouldn't be much with only 3psi and I will slowly work up from there, and I will adjust PE to come in were it is needed. I am going to run 50/50 water meth on a progressive controller starting low and slow on the pump. Is there any tips or tricks that would help with the meth injection? And or any other parts of my tuning plans or am I missing something? Thanks for any help it is greatly appreciated!
