Hello all, I am trying to update my PCM to a ZZP PCM. Its only 80 dollars and I was wondering if you all could help me out. I am driving a 97 GT with stock everything. I’m looking to get a U-bend delete ASAP and a CAI but I am completely stuck on the CAI because there are a millions options for me to go. Right now the ZZP PCM sounds good but I figured I would run it by you guys and see your thoughts about it considering half of you have it. I read into the PCM and it sounds great. Most of all I am looking forward to the limiter coming off, as immature as that sounds. On a side note, if I get a U-bend delete and a CAI, will I need to reprogram my PCM? I may sound retarded but stick with me as I am not completely mechanically/Electronically knowledgeable with these motors. Here is the site to ZZP’s PCM. http://www.zzperformance.com/grand_prix/products1.php?id=182&catid=107 The next thing (after the PCM) I was thinking of upgrading on my car was a 3” DP along with the U-bend delete. Or should I just get a CAI. Also, another thing I noticed was that several people had PRJ wires and aftermarket plugs. My understanding was that the stock wires were the best, but I am pretty sure I am wrong there. And I want to do the plugs but I never looked around to see how difficult it was to access them. Will upgrading my plugs and wires really add some responsive performance or am I looking at reliability here. I am sorry about all of the questions about this stuff but I swear to god that I cannot stop working on this car. I love it and I love watching me turn it into something it never was. I just want to know everything I possibly can know about this car and I can tell you that I don’t know much. But that is why I am asking you knowledgeable people here. Thanks for everything guys. -Jon

I thought about getting a performance PCM but I didnt want to have to pay for premium gas. Stupid reason, but I'm cheap like that. lol.
You shouldnt have to reprogram a PCM for a u-bent delete and CAI. Most people are running those with a stock PCM anyways.

i am like you i LOVE TO WORK ON MY GRAND PRIX they are great cars but i am going to get a new pcm but yes the one down fall is that you need 91 gas but you get diffrent shift points and yes the speed limiter removed .... now about the u bend deleat i wouldnt get it if you plan on getting a down pipe because once you get the down pipe they remove the ubend "i think" or that is my understanding i am pretty shure. and i have a thread saying "what do you think about his FWI" it talks about a cold air intake i was thinking about buying an intake kit but after listening to people i think that i am going to make my own intake but just take a look at the thread just let me know if you have any other questions thanks

Stock wires are the best you can buy. I had a set of MSD's and they only lasted about 9 months. I went back to AC Delco's and everything has been fine since.

Go with the ZZP PCM, as for the D/P just save your money and go right to the D/P only becasue there is no need to spend money on a u-bend del. then spend money on the D/P. JUst save up and go for the D/P. The stock wires are great, no need to change them. The Plugs go with AL104s only because the 103s run to cold. The CAI If you are going to get a PCM and a D/P from ZZP call them and order it an when you are ordering it ask them about there FWI its basically there $10.50 intake tubeing and a K&N airfilter its only like $50 ,cheaper then what you can make it for and less the hassle.

Ok so what i got out of you guys is that I should get the ZZP pcm and that it requiors 91 octane gas? Do i really have to get 91 octane? I didnt know reprogramming a PCM entailed that. Well i dont care ill do it. And next on the list, jsut go for the 3" DP, and build a CAI myself if i get the time. Thats what i will do if i have the time. Now i want to get the ZZP pcm but there are some options i am confused about on the web page so if someone could help me out that would be great. And thanks again for all of your help.

Reprogrammed PCM's require a minimum of 91 octane. I use 93 octane.

What are yo confused about? I was greatly confused too, but I got a ZZP PCM few months ago. Figured out the confusion and the crazy confusion installing it, was actual simpler than I made it out to be. Ask away...

Yes, you need to run at least 91 octane. I use 93 octane.
Get the entire 3"DP and u-bend at the same time.
And as everyone has said, make your own CAI. If you arent inclined mechanically then buy one. I have the thrasher and love it

If you don't use 91+ octane you will get knock trust me I found out the hard way.

yep, the PCM is worth every penny in extra gasoline costs. but i would say do all three, CAI, D/P, and PCM.
Oh yea and PRJ wires are not needed for daily driving. Sure they are great wires but they are big time overkill for most people.
