Well it's been two weeks and about 500 miles since my intercooler system was drained and the de-tuned piggyback was installed. Engine is no longer misfiring, but my gas mileage has dropped to 12 mpg on the highway. I used to get 16-17. I see they have a S/C available for 07 and 08 now. I wonder what intercooler type they chose to go with. I hope they have my new bar and plate intercooler ready sooner than the 6-8 weeks I was told it would take. With gas prices the way they are and that kind of mileage I might have to start driving the wifes Pathfinder.
