Interesting. But get afr to 12.0-12.5. And can't remember now did you copy over the l86 intake volume value as well as the tb value?
Think exhaust may harm you a little bit. Better with that x pipe straight muffler adds just enough back pressure to allow scavenging and little to no resistance at wot.
Also you do not have all the power enrichment or torque management stuff tuned just yet. Then you can beat up on 6.2l trucks.

12.0 to 12.5 is rich for a DI engine, he's doing great at 12.8-13.0.

 

Having the fuel injected directly into the cylinder is a great thing for cooling the air charge.
