I have the Pixie outlaw 5 port in my NTC3. I've run almost 2 gallons of fuel through it and if it feels like running it's a rocket. Most times though, it will run fine for a couple of laps and then lean right out. Absolute total frustration never knowing whether it will accelerate or sputter and die. I've taken apart, cleaned, resealed so many times and have yet to find the problem. I've had every fast guy at our local tracks look at it and no one seems to have an answer. I'll never buy another.
