Whats the best tuned PCM that's available for my gtp? I used to have a dhp in my old 98 gtp, I liked it. I always heard to stay away from zzp PCMs. Just want some input. Any very big noticeable difference? Seemed like my dhp tune woke my 98 up.

They should all net you about the same.
What all is done to it?
I've had a ZZP tune, Overkill, and an Intense. ZZP tune was meh. Saw up to 4* of knock on a 3.4 setup with only 14* of timing at WOT. Switched to an Overkill tune on the same setup, and no more knock. Overkill has a pretty nice 'quick star' feature. I was pretty impressed with it.
I'm currently on an Intense tune (totally different car) and couldn't be happier. Great customer support (they called me and talked with me for a bit about what was done to the car, what I wanted from it, and driving habits) Didn't have to do a security relearn (had to with the ZZP and overkill) and it didnt pop the code for a CASE relearn (though it's a good idea to get it done anyways)
From my experience
Intense >>Overkill>>>>>>ZZP
Its a 99 white four door just like yours. As of now it's stock but I plan on 3.29 gears since I'm getting the trans rebuilt. 3.5 pulley, cai, zzp dp, and res delete. Possibly headers to.
I think any of them would benefit from some further tuning I am going with http://www.gmtuners.com/ Ryan knows his **** and he works with you directly.Not to mention at a much better price.
Overkill was $125 I believe, and my Intense was $140 with unlimited changes/support.
If you're down for a little drive I'll flash a tune to your car for $50
I can just do canned tunes right now but I hope to soon learn more
I'll keep it in mind when i drop a pulley size this summer
