I think I understand the point of stacking, is it wise to do with a stock setup? Will a smarty mp-8 stack actually pay off? From what I understand the mp-8 adjust rail ramp pressures and timing curve, this with a smarty cause a problem? I dont have any mods done now just a curiosity before I make my purchase.

 

With out supporting mods I would advise against stacking. But yes you can stack an MP-8 with a Smarty and get some serious fuel flowing.

 

Smarty and MP-8 play really nice together. You can install a nice exhaust system and cold air intake and with a stock engine get some nice performance. With supporting mods...injectors, moded cp3, Air dog, etc.... thier glory will shine even more but you are not going to damage anything running them on a stocker. Just be sure to NOT run TNT tuning as you will loose rail psi, and also I recommend running the rail pressure adjustment at STOCK on the Smarty as you will be controlling it with your MP-8

 

ok, so i have my new gauges in place for a couple of weeks now(just want to learn what stock does) my rail pressure when i pin it goes to 22-23k then up to 26 close to red line, i pull 27lbs boost out of and never pass 1000 on egt. do these sound right?

 

rail pressure shouldnt go over 24k but guages can be off from the actual sensor, boost is staying at 27 because the gate is opening

 

sounds normal for stock
