any body had any problems or know anything about stacking these two

CTD NUT

This is a bad stack....the Comp has aggressive timing advance on all of it's levels and most programmers like the hypertech rely mostly on timing changes to get the additional power they provide. There may not be any power gain at all and quite possibly some surging and drivabiltiy issues as the result of too much timing.

Try posting in the performance section and you will get many more replies to this.
