When I found Ivans website I was really excited and gave him a call the next day. The current fuel tuners for the stratoliner are piggy back units and are only good for adjusting the final amount of fuel going into the engine, and cannot totally eliminate exhaust popping, and are very limited as to what they control. I was really excited when I saw on another Stratoliner forum about someone being able to reprogram the stock stratoliner ecu and fix some of the fueling problems inside of the unit.
