Are you concerned about your fuel rail pressures? Did you beef up your trannys? I've gotten the VB and TC and I want more power now but I'm afraid to break something on the engine making that much power.

 

I thought that the TST didn't raise fuel pressure?

 

I'm not sure coolslice but how could it make so much power and not raise the pressure? Does timing make that much difference?

 

The TST adds injector duration (it keeps the injector open longer) to add more fuel and thus more HP.

The TST, and the to-be-release Edge Juice, do not raise rail pressure. They only alter injector duration and timing. There are several people who have stacked the TST with a pressure box and the results seem to be pretty good.

 

Hmmmm I wonder if my truck could use a little umph.
As far as stacking goes. Is there anything special you have to do or just plug both boxes in and go?

 

I think the most widely accepted method of stacking a fueling box with the TST is to make sure that any connection points they share in common (i.e. MAP sensor) that the TST is plugged in first, then the fuel pressture box, then the factory plug. If that has changed, or if it makes no difference how they are connected, someone please chime in and correct me.

 

I have the pressure box (edge) plugged in first then tst. So I guess it does not make a differance. i know it is working because each level of the edge increased 1/4 mile time 1/10 of a second for nearly 4/10 total gain. And of course their is no question the tst works. It does change the boost gauge on the tst to read a high level of 20 lbs boost due to the boost fooling of the edge box.

 

You need to flip flop the MAP plugs. TST first then the Edge EZ. Since the TST does the majority of the fueling especially past 23 lbs of boost (or whatever the boost fooling starts at) You will benifit more by putting the TST first on the map sensor.

 

Thanks for the info. Now to figure out how badly I really need another box......

 

Dodgezilla,

Check out Doug's report and matrix. He has very good information about the type of boxes out there, how they increase power, several dyno runs, and even information and some dynos for stacked boxes. Here are the links to the two pages:

Hope this is helpful!

I stacked my TST and EZ together on my 600.
Dynoed 462hp and 845ft lbs with a stock turbo.

Well, it looks like the EZ and the VA box and also the EZ and TST boxes stack pretty well together. What settings are you guys running with EZ and TST together?

 

I see you have an ez, but for reference - I run the tst 3x3 + Quadzilla @ 100 hp setting. egts are better for some reason using the Quad on the higher setting. Go higher like 7x2 + Quad, no problems.

 

Thanks Redram. Man my wife's gonna kill me if I drop another $750.00 on yet another power module!!
