I am looking to get more power from my Expy when towing a boat but don't want the extra power all the time. I read in another Ford-Trucks forum that a switch chip is ideal for this.

Any suggestions for a switch chip for my Expy, where to get one and the cost?

Thanks

 

A Diablo Sport Delta chip is ideal for this. When you run 87 octane you can switch the chip off. When you feel like getting more power and you're willing to run premium, switch it to the performance tune. See here for good pricing and info:
