|Scott's 86 GW, "Super Chief"|
I just did new injectors, new gaskets on the throttle body, and new gas tank. Before that, I had issues I couldn't seem to tune away. Lean spots where I couldn't bump the VE table up any further. I had to increase base pulse width (BPW) to an insane degree and still didn't quite get it solved.
Running the stock ADSU bin, it starts up easily--unlike before--and it drove pretty good but had some serious lean spots at high load, low rpm. I was able to tune those out and the drive back was improved.
More lean spots remain and it's running rich in the low load, low rpm areas. Hopefully I can tune those out, then get on with the highway tuning, and get it ready for emissions later this week.
