Stock bottom end was always happy, just setup your failsafe properly. Tephra will have mapswitching out very very very soon and you will have NOTHING to fear. Yes a retune is necessary to take full advantage of it, you'll want to run 4-6°*more timing and need to yank about 10-15% out of your fuel table while the meth is pumping.

Tons of info in the alky forum, but I like this post best:

Simple facts:
-50whp/50wtq gains with retune
-it's safe
-it's affordable
-its reliable

Umm, thanks. Now I'm thinking about putting my HFS-1 kit out of my evo8 into my X. :P
