The reason you can use the 6 gun with a chip is its basically a glorified 10k mod. With a custom burn from Jody or Tony you wont need the 6 gun at all. In fact if you did stack it you might gain about 5 to 10hp tops

:agree: The most I have seen is 13hp. The last guy that had a stacked setup only made 9hp more on the dyno, needless to say he was a little ticked off.
