DHP went out of business long ago so updates, revisions, support and new developments do not exist. HP Tuners is now the standard of the industry but it is more costly than buying an old obsolete tuning program. Successful swaps have been done using DHP but HP Tuners gives you technical support, an entire tuning/scanning package (with recording capabilities) that is more versatile and allows easier adjustment with more precise tuning. If you want to know what the professionals use, its HP Tuners.
