I am going to order the dd from
I agree that the dd will help with tuning the afc, probably even more than the dyno since the ecu will change a few days after that. I just want to get it tuned and leave it alone but it looks like I am going to have to constantly change parameters to get the car to always run safely and strong.
I have a harness for my power meter and sbc-id that also reads a/f off stock o2 sensor. I just got it and need to hook it up tonight to see if its accurate.
