What are the differences between the Extreme RKL puff tune w/ no timing added and the Extreme RKL puff stack tune w/ no timing added. I want to add my Edge Juice to both for an MPG and power experiment for poops and giggles.
Supposedly they are both 200 HP toons? Any Ideas, I really don't want to melt anything while I find out

 

I run a RKL stack tune with timming, stacked with a Dr.Performance stage 3 works great but im gunna try some new stuff out.

the stack tune is for stacking. it is not suppose to add pressure but i dont know for sure

 

They both say they have zero timing. Just wondering if there is any insight on this
