DHP or ZZP PCM

Which one is better? Why? Is there any other pcm you would suggest for a 98 gtp with K&N drop in, resonator delete, autolite iridium plugs, and a tranny cooler?

a tune tailored to your car is the best, but if youre not planning on modding a lot then a canned tune will work out well. in that case i would recommend a DHP, intense, or overkill.
 
Intense or overkill. But like Nick said. A CUSTOM PCM is way better. And sometime we forget what CUSTOM really means.
