Not sure where you've been shopping for chips, but you should try
here. I really don't think you'll beat the price or the service. I've bought 3 from Mike and will get my 4th from him when I'm ready to chip this truck.
For some engines, chips do more than just add power. Our
Expedition (it's really my wife's) runs MUCH cleaner with the chip. What I mean is that without the chip, the exhaust pipes get black and sooty. With the chip, they are as clean as can be... a result of more efficient combustion. There are no MPG improvements, but she drives it pretty hard. [img]images/icons/shocked.gif[/img]
As for performance at
only 5%, my wife refuses to run her Expedition "un-chipped". When gas reached it's highest price this year, she let me pull the chip for only 1 tank. Even if it's only 5%, that's still 15HP more than you have now. [img]images/icons/wink.gif[/img] I say give Mike a call and discuss it with him. Be sure to ask about the 30 day money-back guarantee.
