I love mine. When i first installed it and was running really high boost i was getting a lean spike right after the boost would hit. It took a little playing around with the fuel map but figured out that the lean spike happened right at the targets i had the Autotune set to turn on. Solution= i added like .5-1% fuel all the way across the rpm where the autotune was set to come on. Example. Autotune triggers= 10 psi boost, and 85% throttle. So at 10psi in the fuel map all the way across the map i added a small amount of fuel. Now my a/f is flat as a board from the get go, and it only happened when the boost was really cranked up.
