#1400 of 1419 stabilitrack by jpete74 Sep 24, 2007 (4:34 pm)
I have an 07 gxp. the question is does anyone have problems whith there stabilitrack turning on in a corner when you are all over it, after you have shut off the traction control and the stabilitrack system. The dealer and a gm engineer tell me that is what the car is designed to do but they also told me you can not shut off stabilitrack. The owners manual showes u how and that it is possible and the gxp only. any info would be great, this problem has me verry upset about the car not performing the way it should.

Replying to: dblduce (Jun 26, 2007 5:07 am) Did you replace just the rear tires or also the front ones?

Replying to: dblduce (Apr 30, 2007 2:45 pm) When you have a chance could you please give us an update on how the Cooper tires are working out for you? Specifically, I was wondering about any adverse consequences you may have experienced since the rear tires were not an exact size match........the overall diameter being a little smaller. thanks Replies to this message: dblduce (Nov 09, 2007 11:41 am)

Replying to: hankpsufan (Oct 30, 2007 9:42 am) Not a thing wrong since updating the tires. The only thing noticable is that going from a 225/50 to a 225/45 makes the rear tires seem "thinner" or closer to the ground than the front ones. but if you measure from the ground up to the bottom of the rim in both the front and rear wheels, its the same. Since I changed the size of the rear tires and not the fronts, it doesnt have any impact on the speedometer, since its driven off the front wheels/transmission. I have had no other problems whatsoever. They have been great tires for the past 6 months / 5,000 miles I've had them.
#1404 of 1419 Eagle F1 All Season by jehu75 Nov 09, 2007 (12:17 pm)
I would highly recommend the Eagle F1 All Season. They were expensive, but the performance I am getting out of them is as good, or better, than the 050's. Highly recommended and no change in tire sizes.
#1405 of 1419 my maf sensor by mcrowe Jan 13, 2008 (3:30 pm)
I recently have a problem with my 00 pontiac GTP . It seems flooding and runs terribly , black exhaust smoke. Then 1/2 hour later start run good for a minute then it was back to running rough and die. I unplugged the MAF sensor and started it ,ran fine. I drove it 168 miles home. Service light on now though never came on before. Just wondered if anyone had this problem. And if it is the MAF sensor. Replies to this message: jpete74 (Feb 20, 2008 7:42 pm)

Replying to: mcrowe (Jan 13, 2008 3:30 pm) most likely that is the fault of the maf u can actually clean it will carb cleaner but be carefully not to touch the fine wires in the middle they can break easy. if that does not take care of it try replacing it. the check engine light probably will not go out on its own, you will have to have it shut of.

Replying to: gxprix (Sep 15, 2007 5:28 pm) My friend has a HP tuner and we plan to put a tune on it this Spring. I will post this Spring on how it worked out. I know a different pulley would add some power, but I think you need to yank the engine for that. Sounds like you've done about everything you can so far. Do you feel a difference in power from the mods you've done so far?

Replying to: gxprix (Sep 15, 2007 5:28 pm) Just wondering if you had gotten any replies or found anything for mod sites for a GXP. I found stuff for the supercharged but nothing for the V8's. How did the intake and exhaust work out? I am looking for an exhaust that will add some sound but not be overly annoying. Any suggestions? Replies to this message: gxprix (Jul 01, 2008 2:24 pm)

Replying to: seanmckean (Jul 01, 2008 10:02 am) I have not, it seems that everyone has ignored my question (not a very good message board). I have moved on to LS1tech.com, much more superior to this garbage.   To answer your question, the flowmasters were awesome. I would recommend removing the resonator as well, to get a very nice deep sound. To give you an idea, it sounded like an old Monte Carlo or 305/307 Chevy V8 motor. The intake was cool too because it gave the car a supercharger sound when it sucked in the air, I saw a small increase in HP as well.
