Engine/Transmission (1998.5 - 2002) stacking programmers

[MDSlover]

would it make a difference in power if you stack the edge ez with superchip 3855 flashpaq will it hurt anything ihave guages so i can watch egt

Yeah, it can blow your headgasket to bits.



I had an Edge EZ stacked with an Ottomind and it was too much timing, among other things, for the headgasket to handle. Advanced timing can create higher cylinder pressures.

Yes and no... ... ..... If you use an EZ which is a timing box with a programmer with a fuel only setting then yes it works well but as posted above too much timing can be a bad deal. Smarty has timing only and non timing programs not sure of other programmers. You want to stay away from using the timing of 2 products together especially when towing. Timing of one product with fueling of another is best.

Stacked boxes

I've used an Edge EZ and a TST Powermax 3 stacked for about 6 years now. I run about 38lbs. of boost and my truck runs great and averages 21mpg. I've had no issues with it. I took off a Banks Ottomind kit to put the others on. My truck has 152K on it and I'm looking at replacing the injectors next. I will upgrade to a better fuel system when i do the injectors though. Stacked boxes have worked fine for me.

Figure that the EZ gets just about the most fuel out of a non-wiretapped VP44 as possible. So will the Superchips tuner. So from a fueling standpoint you wouldn't get any more peak power out of those two gadgets stacked, since either one takes it to the maximum. But as stated above, the timing advance does add together, which will get you a new headgasket and egg-shaped main bearings.



The TST/EZ combo works well since you'll get the timing advance and throttle curve of the EZ and the extra fueling from the TST via the pump wire tap. Effectively the same thing as a Comp, but using two boxes. If you already have an EZ and are looking for a good HP return for your dollar, this would be the way to go.
