whats the best chip for a 99 cummins
 

i have a 99 cummins. its an auto. i want more power, smoke and mpg. whats the best chip?

Moved to the correct section for ya...

The Edge Comp Box fuels very hard. It has no fancy options, all power. The Edge Juice with Attitude gives you power, and a monitor for engine parameters. As you might be able to tell, I prefer Edge.

so witch of those 2 do u like better?

I would do either Edge CTS or Edge Comp and Mechanical Gauges

TST powermax 3 comp

I love the power and simplicity of the Comp. With it's lack of turbo timer, alerts, and gauges, I keep the EJWA CTS in the truck most of the time. If I had to choose one and never switch back, it would be the Comp and I would get more mechanical gauges. Fortunately, I don't have to make such a life altering decision. :yeah:

Im with RAWilliams on this one, Edge Comp box. Its simple, smooth and makes alot of power for the dollar.

It doesnt have a gauge one so you have to do all the some other way, in my opinion all you really need for gauges are, EGT and fuel pressure and if you tow with it maybe trans temp.

Edge J/A hands down. A lot of people like Quad however I don't, but that is also an option. TST makes good products as well.

Don't forget boost pressure! The head gasket can fail if you push it too hard, and a head gasket failure can cost just as much if not more then a IP failure from low fuel pressure.
