Precisely why I feel better dealing with the only man I know who is running a custom PCM DHP chip and who has tuned it for the best possible performance from our cars. I may pay a little more but Scott has put a lot of effort and research into our Bonneville'* PCM and performance options along with his contacts at DHP
The DHP 1.0 is a basic model PCM that will be the same no matter who you order it from.
And yes, it will be specific to your VIN # whether a GTP or Bonne.
The DHP PCM that Scott uses in his 11. sec SSEi is very much more a custom unit.
We won't be needing that one.
Intense doesn't even list PCM'* in their product listing.
..and quoted from their performance recipes:
"restrictive PCM (much more aggressive traction control system cannot be overridden by simply pulling a fuse; PCM will actually retard ignition timing if you try to power-brake the car)
no Performance Shift function (so shift points are lower and shifts are slower) "

Info on performance shift..
Ok guys, sorry i didnt get a chance to reply sooner. On regards to the performance shift issue on our cars... jason jeross refered me to www.clubgp.com also and here is what I found:
I found this on http://www.rivman.com/perfshift.htm
Now keep in mind that this is still refering to a GP. My only suggestion and what I am going to do is take a look at my harness and if there is nothing on pin 21 of the clear harness, I am going to consider this as not having performance shift active. I really dont see Pontiac going through that much trouble to have a completely different harness on our cars than a GP so I think that would be a safe guess to look at that pin.
One question though jmp417, you already have one of these pcm'* in and did nothing. Have you noticed any change in shift times or shift strength? Per the specs on DHP'* site, the pcm changes the shift point from 5800rpm to 6000rpm. If you are getting that, then our cars are most likely already in "performance mode", if not, i would guess otherwise. If anyone finds out before i get a chance to rip into mine, let me know.
Silver:
As far as dealing with ZZP, I would think that if you can buy a product direct from the manufacturer, that would be the best route and at the moment, DHP is offering just that and jason jeross told me that if ordered, the pcm would be out the door in 2 days.
Also, back to the tranny cooler issue.. Now I have also read that some people just add the cooler to the existing system while others totally cut off the circulation to the cooler in the radiator and just use the seperate cooler. Suggestions? Comments?
How to add Performance shift back into your 98 - 2002 GT/SE, and 2000 - 2002 GTP:
Following these instructions you should be able to add a performance shift switch to any 98-2002 GT/SE or 2001-2002 GTP equipped with a Digital Horsepower PCM.
Parts Required:
1. About 10 Feet of dark blue wire 16/18 Gauge Preferably, use your own judgment.
2a. A Shift **** from a 97-2000 GTP (GM part #10224212)
2b. OR any type of "On / Off" switch.
3. Packard Electronics FEMALE Connector Pins (GM part #12084913) Sold in Strips of 5.
4. A DHP reprogrammed PCM
5. Misc. Wire connecting supplies
Instructions:
1. Disconnect your battery
2. Remove your air box, locate your PCM and remove both connectors, this will ease the job immensely.
3. Locate Connector 2 on the PCM that will be the Clear one NOT the blue one.
4. Lift off the gray covers covering the wiring you may have to cut off some tie wraps to do so.
5. Locate Pin Number 21 or lack there of it will be a empty slot, take a drillbit or a punch and punch a SMALL hole in the rubber covering it.
6. Take one of the FEMALE pins and crimp the Dark blue wire onto it at the end. You may want to solder this connection as well to avoid any problems in the future.
7. Push the Pin and wire assembly into the whole you just made in the rubber grommet at pin 21 on the clear connector. MAKE SURE it seats fully, it may take 2 or so tries to get it right.
8. Position the wire to run with the rest of them out of the connector and into the loom if possible, if not grab some loom and cover it, a factory appearance never hurt anyone.
9. Take the aforementioned blue wire, now connected to pin 21 on your PCM and run it into the cabin either way you see fit..
10a. Run the wire up into the console and up to your NEW shift **** with switch, attach the blue wire to the RED wire of the switch using whatever means you like, solder/butt connectors ect, take the black wire on the shift boot and put a knurled ground loop on it and attach it to the upper left hand corner bolt that holds down your shifter.
10b. If using a simple switch, solder the Blue wire to one prong, and solder the ground wire to the other.
11. Reverse all procedures and button up all your trim and underhood accessories

PULLEY?
I would scan first after your 3.4 and pcm to see where you are KR wise. If it looks good I would drop to a 3.2 and rescan. If you see KR (and you probably will) rockers will help and with rockers and headers you should be able to do a 3.1 or 3.0 pretty easily. While your doing rockers you may want to think about pushrods. Pretty much you will want to scan as you go to make sure your not running too lean or producing to much knock.

I think we all have the ZZP modular pulley system from ZZP or Intense. They sell puleys in .1in icrements. 3.8 down to 2.6 I belive, might even go smaller. Lot of guys will run a certain size pulley on pump gas and go down .1 with race fuel at the track.
Press on pulleys usually go 3.4 or 3.5 than 3.25 to 3.0 and so on.

OK. as far as pulley manufacturers... Who makes a better modular pulley. I like how both pulley boys and thrasher make theirs look pretty well stock and ZZP'* is completely different.. So who has thoughts on this?
Also.. what did you guys think about my cooler question?
"Also, back to the tranny cooler issue.. Now I have also read that some people just add the cooler to the existing system while others totally cut off the circulation to the cooler in the radiator and just use the seperate cooler. Suggestions? Comments?"

With the trans cooler, let it go through the rad first then into the cooler and back to the trans. This is the way the factory does it.
