I am looking at purchaseing a Dr Performance predator chip from someone that has it on his 04.5 dodge and I also have an 04.5 dodge. How good are these chips? Also when he unplugged it from his truck, it started missing and then when he plugged it back in it ran fine. Any ideas what the problem could be?

thanks

 

They have the reputation of being one of the worst all time products on these forums.

Can't say for sure why it would miss when taken off the other truck could be a loose connection or perhaps it works by increasing pressure to the injectors and one is now worn out and only becomes noticeable when the pressure drops.

 

The Dr. P is a very aggressive pressure box.

You are better off to find a different power adder; the added costs down the road are not worth the money you are saving by buying the Dr. P instead of a different item. See current owners issues.

Take a pass on that one.

 

My dad has a 85hp one on his 03 cummins and has never had any trouble out of it.
