Anyone try installing SuperChips or anything else to improve the performance of their vans. 0-60, 50-70, and pulling power are all areas I'd like to improve.

 

I installed a condensonator on my 02 E350 15 Pass. huge difference in power, and a marked increase in fuel economy, about 20%. They are aout $200, and easy to install yourself. We go back and forth to California each year and pull our tent trailer. Going over the Siskous in Southern Oregon always gelt like a chore with the trailer. After the I installed it and took the trip, pulled up the mountains like nothing, and get this I got the same gas milage pulling the trailer through the mountains as I did pulling nothing.
Here is their website for more info.
