Performance Loss???

[Tha187um]

Is there such a thing as Tire Break-in period as well? I have 3,400 miles so far. One thing I've noticed is that I used to easily make the tires peelout even without trying... A few times I've turned off ESP and used the autostick and floor the accelerator and the tires would peelout for 2 - 3 seconds before the car would launch out with a good grip... now I try the same scenario... Shifted down to 1st, ESP off, Floor it, I launch but not a single squeek out of the tires... Did I lose power or is this normal as tires get older?

could be very possible the tires are grippier after the first shiny layers of rubber are scrubbed in and any somlvents used in the tire making process have blushed out completely. However, it could also be the torque management trying to save your very expensive transmission/rear end.

I like the tire concept better

But if it is the Torque Management as you also mentioned, would that be a sign that transmission is going bad? Its not like I peelout every day, I tried it yesterday and thats when I noticed it and for the hell of it I tried again this morning and same result.

I doubt it. I think the tire gaining grip is more likely than some loss of power out of the blue. It's just good to have a couple viewpoints as to what may be going on.I have only done one burnout in this car in the year I've had it. It was in a newly paved and damp parking lot. Not much of a challenge to light 'em up, but also not a lot of strain on the drivetrain either. I got applause from the passers by, so it must have been a pretty good burnout. And only doing one in 20,000 miles I think shows remarkable restraint, for which I am not usually known.

Torque management has Nothing to do with take off power. Essentially, TM is a process that dials back ignition timing during upshifts. IT was original used to soften upshifts. It was then realized that it also prolongs tranny life. Tm is used on just about every vehicle on the market now. It has been used on Chryslers since 1995 i beleieve. I think your issue maybe tire wear. Mid life tires has the best grip characteristics. Could also be tied to fuel type. Chrysler Pcms generally have a very large window of adjust for fuel control. This is call adaptive fuel factor. This is the area of the PCM that controls all outside factors such as octane. Barometer, air temp and airflow.

Ok... not a 100% sure deal, but check this out... I get home and I inspect the tires, there was a THICK layer of sand on them, I mean thick, I don't know from where... but I washed them off and took it for a spin, again, not trying to do it, tires peeledout a bit... I will check this over the weekend and post back... thanks for replying guys...

What tires are they? Good Performance tires tend to squeel less, because they are making forward motion and gripping the road. Squeling tires are cheaper less grippy tires that is only spinning around and not making forward movement. The more noise the slower you are going. Tire squeel is a bad thing.

I agree with you, and though I might have seemed disappointed that I didnt hear them squeal, I was just concerned that why would tires stop squealing all of a sudden... I have the self sealing tires from factory which I've heard they suck.

They do suck, but I'll say this, I've NEVER had trouble pealing out in this car, it pretty much does it on demand... In fact it took a few launches before I got my 5.68 0-60 on my G-Timer... I feel I can do better than that also, but it satisfied me and I kept it for now.... With spring approching, I will be trying to better that...
