Hey, guys.

I have been running the X2 for a while now with good results. Now I'm ready to play with a Smarty stack. I'm still new at stacking, but I understand how it works. I just would like a good baseline to start at. I do still have the stock clutch, but it holds very well to the #5 race setting on the X2. So, I would like to know where to start. Also, any other information would be greatly appreciated. Maybe a good mpg setup and maybe a good power setup????

Thanks, ERIC

 

I just recently swapped out the Banks for an X2 Race. This thing is insane. The tranny started slipping the first time I took it out and even w/ the X2 on level 2, my fuel pressure goes to 0.
So, as a word of warning, be careful running these two together w/ stock clutch and lift pump. For around town I have the Smarty on 6 and have the Race City MPG tune on my X2 w/ it kept on level 1 (mileage). Then if I want to turn it up (and destroy my tranny) I bump up the X2 to 3 or 4. Another thing to note, EGTs are much higher w/ the X2 Race. Enough that I actually need to keep an eye on them until I get the new turbo installed.

 

Thanks. Ok, so does the X2 add timing with the stack tune? Or should I let Smarty do timing? I'm going to go with a Southbend clutch in the future, but for the time being, I want to use a conservative tune. I was also wondering a safe limit on rail pressure? I'm still new at the stacking.
