I have a 01' Gtp still in warranty. My mods as of right now are as follows: 3.4" pulley, Wizaired CAI, Dynomax Exhaust w/ U-bend removed, Ngk TR6's, Throttle body screen removed,
160 stat. My ? is do I get a DHP PCM or 1:9 to 1 rocker arms next? I don't want to get the PCM because of the warranty but I think it would help. As for the rockers they will give 25 whp which is way more then the PCM.
Tough decision, please help....

I'd highly recommend the PCM first. The PCM will take better advantage of the mods you already have installed and you'll be much happier. As for warrenty issues you could forfit the core charge and keep your old PCM and swap them out when you have to take your car in for service.

Agreed.

What do think I should run in A 1/4 mile with this setup before and after the pcm?

It's hard to say. Every vehicle is different. How you drive plays a big part of it. But put it this way PCM, Pulley and Ubend delete are the basic mods to start with everything else is built up from there.

After you get your PCM, put a 3" D/P next on your list, you'll need it.

Just wanted to brag... got my Jimmy C DP in today. But, I won't be able to get it install 1-2 weeks. Don't have time and I want to get my GMPP Handling Kit, brakes and maybe rotors done next week. If I only had more money....

Off topic. Austin, you gave me the same advice. Can you please tell me what the 3" D/P is.

The stock D/P might be the most restrictive part of the exhaust. The stock D/P can be the cause of as much as 4* KR, if you have a 3.4" pulley on your blower. Replacing the stock D/P with a 3" D/P will allow the car to breath much easier.
Here is who I got mine from. His sight is informative about the D/P.

The 3 things that I've done to my car that I really got some gain from, were the 3.4" pulley, PCM and the D/P.
If you're going to install a 3.4" pulley, you will need to also install a PCM and D/P to get the most bang for your buck out of the pulley. If you do a pulley without a PCM and D/P, you don't have a clue as to what you're missing.
3.4" pulley = waking up with a glass of water.
Pulley/PCM/DP = waking up with a cup of strong coffee.

I would wait to get the D/P installed anyways, atleast until you get the handling kit in. When you install the front sway bar, flip it left to right. This way your D/P won't be rubbing against your sway bar.
Right Canadian?

BTW framos... did you get the GenI or GenII flex joint, or do you know?
From what I read on his site, the GenII doesn't whistle.

It's amazing how a little rubbing against the sway bar can totally ruin your ride... I don't recommened it... I DEMAND IT!!!!

Austin is right a DP should be a priority and when you remove the stock DP you will see why ,saying its a total piece of crap is an understatement ,another part of the exhaust you should consider is the stock exhaust mnflds either get some decent PEM's or headers.

mmmm...headers...
