Programmer Questions
 

During my quest to reach 500hp I am trying to figure out the benefits of two different boxes or programmers. From what I have read the Smarty S-03 Flashes and reprograms the ECM and advances injection timing and spools the turbo sooner thus giving better throttle response at lower rpm's or lower in the power band. The TST Powermax3 on the other hand is a fueling box and does not advance the timing directly but lets the ECM do it and gives more power on the higher end of the power band. With these two stacked, would they compliment each other and play nice together or would they create issues? So the Smarty is a programmer and the TST is a fueling box?
