Just picked up a 2009 Nytro xtx with Stage 1 MPI Supercharger 6-7 boost. Cold air kit and extra fuel pump running @ 500' ASL. Have water temp. oil temp, AFR , and boost gauge. The gems settings are at 3,3,6,2,2,8. Light cruise 35-55 no load afr are 13.7-14.2 any suggestions ?

Thanks

Call Matt at MPI. They reprogrammed mine for low altitude. I bought my kit used and sent it to them

Your A/f at light load, cruising should be high 12's low 13's. As long as you are seeing low 12's or high 11's WOT. You are good. If you want to do yourself a favor, look into Schyco Sled's Bridge for the Nytro with super or Turbo. I installed it and this is the first time I have been totally happy when riding at all elevations and temps.
As for any specific setting for the GEMS, read up on the functions and what setting does what, because it changes daily! Due to temp's, barometer, etc.... with the Bridge system, just ride!
