on the 04.5 up trucks 50 hp nozzles gain you 2 mpg. they extended fueling duration to reduce peak heat. this restores the proper duration, above 50 hp you start to see a reduction in mpg, we think it maybe a atomization problem

So you saw a 2mpg increase first hand on your truck. I only have a stock turbo and already have some black smoke when I hammer it will there be even more black smoke now. Thanks.
