On the vp trucks can u stack the smarty programer with an ez box? Will it work ok?

 

Sure. Just use the tunes that do not add timing.

 

That would be a pretty good stack. X2, keep off of the timing levels on the Smarty and all will be good.

 

I ran the Smarty stacked with the EZ, ran timming on the smarty, seamed to work just not on 9, had to run on 7. Couldn't pull a load on 7 but 8 worked okay if it was a light load, anything heavy i backed it down to 3 i think it was. HAd that turbo blow up last fall and the injectors craped out so now i'm **** near stock,

 

Run the Smarty on even levels and you'll be just fine
