So having that that, do you suggest going BACK to the 87 or 89 octane which means poorer performance? I use Mobil 1 synthetic 10W30 motor oil and change it every 5K miles. I try to care for the vehicle as best I can, and also purchased the exteneded warrantee with it, so I'm covered *bumper-to-bumper* for 7yrs - 75K miles.

Thanks for the feedback.

Id go back to the 87 after that bottle of Gumout you put in your tank to see if you can tell the difference. If you need the performance, the 89 wont hurt, but first see if the Gumout helped any. I know whenever i pour a bottle in mine every 10k or so, i can tell a slight difference. If yours had never been done before then those injectors should be nice and clean for the 87 octane. Remember "dirty injectors rob your horsepower and your gas mileage" -AutoZone[8D]

 

OK good tip. I'll keep you guys posted. I've been shopping around for a SuperChip (eBay etc..) and boy are they expensive.

 

Superchip/hypertech they are basically the same thing. Here is a website to keep an eye on where you can get a new hypertech programmer for significantly cheaper than anywhere ive seen (besides ebay, but i dont trust ebay for items such as these)::-

Looks GREAT, and yes .. certainly MORE affordable. However, I don't see the 2004 4.7L Dodge Dakota in the list. Come to think about it, I didn't see it with Superchip either. Is there a reason why this year, make and model are not displayed?

Thanks for the valued link and information.
