Just want to pick a few brains on this one. 2006 Apex motor Impulse Race Kit 2871 Tial turbo. I am getting codes 13, 15, and 20 sled runs but can't seem to keep it running in the 12's on the Air Fuel guage. Idles in the 13's and as I accelerate and it starts to make boost at say 2-8lbs and 7000 to 8500 RPM it will go rich and run at 10 on the A/F Guage. Which makes it hard to ride cruising across a meadow, blubbers and runs rich. I have tried different controllers and the same results if I take away boost fuel in the middle I can't add enough main jet to make up for it. I have had my controller remapped and that has helped but not curing the problem. Using a Purelogic controller and I have a stock Attitude controller as well to compare with. I know some of you guys don't like these controllers but I have had 4 good years running this one.
Because of the codes I think I have other issues, have done all the tests , swapped computers and all the sensors and no luck. In Diagnostic's D2 it shows 95 and on D3 it shows 9 that seems like a huge spread for atmospheric pressure change on a not running engine. The manual doesn't help me out and tell how much difference there should be. I have pressure tested the system and I can't find any leaks, tested fuel pressure changed plugs etc.
If the Map sensors are not working properly that would make sense of what is happening the sled is fighting it self. It's telling it to add fuel and it does not need it. ANY HELP GREATLY APPRECIATED
