3800 Pontiac Grand Prix need more Power

2008 is a can bus system, thus not tune-able. Its a year only thing.

1997-2007 cars can be tuned because they are not can bus, though 06-07 have to use a 04-05 PCM for it to work.

So your pretty much outta luck there.

if my 3800 can not be tuned or top swap'd then why is there a giant forum with a parts list and how to do it. I just got back from the Shop with my list and my guys are telling me it's the best way to go safely

This info is not well known to most and is not really a hot topic around here. Its not posted in many spots.

Why do you have to yell at everyone to read this and that? Perhaps post a link from time to time or actually share some knowledge you have stored in your peanut sized brain.

If so, you're trolling us or your shop is trolling you.

If this thread hits page three its locked.

If you post this again, you're gone.

Not being rude, just trying to get the point across. The guy just joined today and hasn't done any research. And although the topic may not be common, it has been discussed enough to be well known and easy to find.
 
no not my original list at all the list posted in the forum is the way i want to go " im not trying to piss anyone off im just looking for helpful info on how to boost my 3800's hp is all i now realize threw the members of this site that just bolting on some parts is not the answer so im going about it the proper way which is the way the forum has explaned which is what I took to my shop im not Trolling any one nor is my shop
 


if you put a sc on you still cant tune it.

im pretty sure you could do headers and rockers with out a tune. and pick up a few hp, not enough to be worth it im thinking tho.

or trade it in for something older, like a few have done here. sounds f'ed up but thats the deal.
 
Get an intake of whatever you want...doesn't really matter.

Buy some Speed Daddy headers from EBay...

Get an HV3 upper insert from ZZPerformance...

You can also get some 1.8:1 roller rockers from any vendor as well for some extra top end performance.

But seriously guy, click the link in my sig and read...do some research.
 


Did they make supercharged grand prixs in 08? If they did then you could do a motor swap with the supercharged motor and use that PCM, you'll also want the trans from that car.
 
well TY for the help lad's I guess im screwed looks like ill be going back to my 2002 Pontiac Grand Prix SE and giving the wife the new one so I can do some Tuning
 
Wow sounds like either way your screwed. Not really to much to be done to the 3100 in that SE.... try selling the SE and get a GTP maybe.
 
waa Should have just waited and got a 2008 Pontiac g8 GXP :( just love the Grand Prix so much wanted 1 for the last year they were produced so i could do it up oh well looks like ill just put a *****ing sound system in it and flare it out fer all show no go lol
