What in the steel? Are you doing any normalizing cycles? Most of the time if a blade warps it is either because stress was induced by uneven grinding or because stress was already in the steel and the grinding simply released it. Either way, normalizing could be helpful.
If you are normalizing already then you might try just profiling your blade, doing the HT, and then grinding the bevels. I've done it this way for 20 years, lots of guys do. This method avoids a lot of stress related problems and, if the blade still warps, its usually much easier to straighten the blade if you haven't ground it yet ...
