Okay, I'm at my wits end with the performance of my car

I have an 06 Magnum SRT and mine is "boggy" coming off the line as well. Mine is however stock except for a K & N CAI and has 7600 miles on it. Although it has just started running somewhat better it seems. Someone else told me that these cars didn't really run as good as possible until they reached around 7,000 miles.
Don't know how TRUE this is... but mine only has a two stage ESP and hardly EVER spins the tires!!!

 

Nothing yet. I still haven't been able to find the vacuum leak (intake/exhaust) suggested by the outrageously large long term ADAP %'s (fuel trims).

Well, I'm almost to 17,000 km (~10,500 miles). Mine has been this way from day one.

Two other 09 SuperBee's in this area are not experiencing my issues. Joe's is running an Airaid CAI with SLP mufflers (no Predator tune). TJ's is using the canned Perf 91 CAI Predator tune (with WOT Fuel adjustments), Arrington 85mm throttle body, homegrown CAI (R/T bottom, SRT8 top with duct work), long tube headers, cat-delete mids, and Flowmaster mufflers. There is no lag off a dead stop in either of them. TJ's can overpower the ESP from a dead stop spinning all the way into second gear (chirp).

We swapped in his stock TB and there was no change. We swapped in his 85mm TB and there was no change. We will be putting his TCM in my car this weekend to see if there is any difference. And, as soon as I can find someone with a Starscan (for free as I'm out of work), we'll write my VIN to his PCM and I'll try it (as it's dated six months earlier)

Will be trying a couple of other things this weekend too. Pulling the intake manifold and playing around with the power interrupt to the ESP system.

 

wow brother, im sorry for your frustrations, i certainly hope you get it resolved

 

You may want to look at your O2 sensors. My car was getting the same symptoms as yours.I thought I could have a vac. leak and did all the checking to no avail. I went ahead and changed the front O2's and problem solved. I never threw any codes either. Good luck.

 

Yes, that is also on my list as soon as I have funds available. Good suggestion. I realize $120 isn't a lot of money, but right now it is. This and swapping the injectors from side to side has also been mentioned.

 

If you don't have the cash, maybe you can swap O2 sensors with a buddy. At least you'll know the cause. Don't forget to use anti-seize on the sensor threads and a nice wrench like this (http://www.amazon.com/OXYGEN-SENSOR...6?ie=UTF8&s=automotive&qid=1253850197&sr=8-16) will help.

 

I bought the O2's from HHP for around $25.00 per sensor and you should be able to get a small shop to put them both in for around $30.00.

 

No worries. Have been horsing around with O2 sensors in my Harleys for the last two years, so a small dab of anti-seize is normal.

No need for a shop to do them, I'm fully capable. No chance to get sensors into Canada for $25 US shipped. If/when I have money, I'll check with Adam at Eastway. I bought my TPMS's from him and saved $60 (after shipping) from ordering them locally.

 

No worries bud, we'll get it all worked out. Meet you at the "Bee Hive"...LOL
