Need some opinions on all the different pressure boxes. Of course this is used stacked with something else. How does it perform? How are it's manners in regards to rail pressure? Spikes? Smooth increase? Blows injectors? Need all the opinions about every aspect of any pressure box you've ever run.

 

I'm still kinda new to the pressure box on my truck and I don't have a rail pressure gauge, but I can say that it's really smooth power. Take off with things turned up is pretty violent and I wish that I had a built tranny so that I could experience a boosted launch with my stack. Top end is QUICK to pick up...from 65-100 it's just pretty unreal. I mean, I don't have a 12 second truck by any means, but to ME, it's FAST. 0-60 in 5.42 seconds = faster than a Mustang GT and I raced an Acura Integra GTR on the highway (65-100) and did to rice exactly what is meant to happen...I COOKED it! I turn both boxes up (cept for Edge, it goes to 5 rather than 6) and I also get the best mileage that way...all in all, I LOVE it. They just work really well with each other...I can't WAIT to get some better fueling and tranny...it will be track time every other weekend at that point!

 

Cool. Who else? Shane I know you have the Mp-8 and a rail gauge. Let's here it.

 

OOOH you seen me learking!! I love it!! In my opinion probably the best pressure chip out there. I haven't had the quad race but the low end grunt in unreal!! It totally woke my truck up and I know it helps spooling the large turbo!! I know Cquestad runs one and loves it too he talked me into it and I don't regret it at all. I will be dynoing May 19 so I will have some numbers but honestly with a stock turbo and stock lift pump, injectors I have not drained my rail once and that was runnning it on 40% and Smarty on #9!! I can get my Fuel pressure down to about four but once the gdp kit goes on it won't be a problem at all. I know wiggs roasted his injectors but after talking to him it was a faulty wiring harness and not the mp-8 total fault. I haven't heard of anything else like that so that was good!

Just my

 

The most ive seen on the rail is 23K

 

Ive read on hear numerous times that you need a fuel pump with a GOOD filter or you'll kill your injectors with any preassure box. No problems yet on mine but I have the FASS system. Definatly notice the preassure though and with the smarty it is awesome..
