I wanted to know what aspects a pressure box affects on an engine, and also I am soon getting a van aaken c3.2 and wondering what pressure box would be good to stack with it, also what type of supporting mods would I want before I stack or should I stack? and if I do stack what brand would people suggest? I know there are alot of questions here, but it should open a pretty good discussion I think. Thanks.

A pressure box does exactly what it sounds like, it increases the pressure to the injectors. So if you are seeing 23000 psi right now on a wide open run, if you had a pressure box you could see 27000+ depending on how it is set. They are great for throttle response and improved mileage, but can be bad on injectors if used at the real high pressures for extended periods. Some choices are MP8, Quadzilla, Dr. Performance and some otheres I can't think of right now. I personally would run a rail pressure guage with a pressure box to make sure you are on the safe side of things.

I'm not sure about stacking with the VA3.2, but I prefer the Quadzilla as they provide you with a rail pressure gauge. Plus they have a number of updates and I don't think the MP-8 is updateable.

Clint, I had a TS Ramifier (100HP pressure box) stacked with the VA. The low end power was unreal. But it smoked way too much and contributed to the excessive wear to my rear tires. Of yeah, EGT's will sky rocket with that stack!!! Get gauges soon.

You can purchase a used Edge EZ very reasonable, less than $200. The older ones had 4 factory settings, the newer ones have 3.

Not only are they cheap, they stack well with most timing/duration boxes and programmers, and they provide additional boost fooling!

Love dr.p, low egt's and great mileage, i likee to keep it on toggle switch though

stock injectors don't like pressure boxes, atleast mine didn't. I got a ez at 90k and went thru three injectors before 100k. I would look for power elsewhere until you get a set of stix.

Ditto, the Quad X2 works well and has a rail gauge, have only had mine up to level 3 of 5 so far and stacked with Crazy Larry it's a lotta fun but smokey when you lug it even a bit.
Watch the calssifeds on the forums for some good deals.

What level were you running on your EZ? The newer EZs no longer have level 4 or the "secret" 5 and 6 levels.
