does anyone know how much pressure the pressure boxes raise pressure to?

I started playing (again) with the TST box some more... put the standard programing back active and put it back to the timing only setting (#1) then bumped the rail pressure by 1k, then by 2k... obviously a noticeable bump in power but my question is how much do the pressure boxes raise their pressures to?

 

as long as you dont go over 24K you'll be fine.

just remember it's hard on the stock CP3 to generate that type of pressure and flow at low RPM's. now mod the FCA and inlet pump and your good to go

 

It's interesting to see what rail pressure combined with timing advance does in 1k increments... for every 1k of rise in pressure, there is noticeable gain in across the range power.

I saw the CP3 mod a while back and saved a copy of the instructions... looks pretty simple.

 

if I had my hands on a good FCA I would pop mine out here at work and hit up the machine shop and mod it.

did you see the orifice hole mod for the inlet pump. seemed pretty straight forward. probably wouldnt gain much stock.

 

I dont think you'd gain anything from it stock or mildly modded... the only time you'd start to see gains is when your pressure wants to drop off due to lack of volume... once the mod is in place the volume will keep up with the demand.

I think i'm going to run around for a while with the tst rail pressure set at +2 on standard programming timing only (1). One thing I have to admit on the new s/w is there are too many things to play with lol... making it hard to decide how to leave it. when I went wheeling the other day I left it in an econo program set to 4/3 IIRC and it used up a ton of fuel while wheeling... far more than the old program. Next time out I'll have to remember to turn the box back to stock since you dont really need it back there anyway.
