I am noy getting the boost I think I should be getting and I lose power on level 3 on the Quad race. I am about to pull the trigger on upgrading to the
X2 race with the pressure only tune but hear great things about the MP8 also. I feel like I am on a first name basis with the crew at Quadzilla and enjoy the fact that I can always get a hold of someone that is knowledgable and helpful. But the final word is what will work best on my truck. What is your guys opinion on the best mate for the Smarty? Thanks, Tom J.

 

I ask yesterday and was told the Smarty 4.4 will have about 25k of rail pressure.

 

4.4 does do 25k rp...but only smarty 4.4....none of the other versions have pressure....except perhaps the new race tune...with your mods you should be running one of these versions anyhow....

A lot of people like the MP8 with the smarty...that being said, i'd think i'd try the pressure only tune first...it adds pressure (obviously) and you can then utilize smarty's dynamic timing....and it's free....

 

I have really liked the Quadzilla pressure tune. It works well on top of the Smarty.

 

X2.................
