for you guys with modern Hemi's find a dealer mechanic that knows what he is doing ....on this. and you should see an improovement in et/mph.
have him check and calibrate the TPS throttle position sensor... they are all over the place.

the timing curve is based off this.
and also check the range on the MAS..
oil consumption will cause detonation which will cause the ecu to dump ignition timing..
all three of these will kill 4 mph..
cheapst.

OMG!!! Look what happened............

You had a nightmare, woke up and your chally came back as a camaro

I have to say the challenger looks sooooo much better. But at least you have some power with the camaro. Congrats!!!!!

Saw an automatic SS Camaro out at RT66 yesterday. Conditions were pretty good, and he was running 13:80's.

Welcome to world of the LS3!

Congrats Ron! I raced a guy in a 6 speed SS car twice at the track, once in time runs, once in first round. This was the first new Camaro I had ever seen, supposedly the first SS in Washington State. Admittedly the guy told me before hand he is a very poor driver and only had 250 miles on the car.

Both Passes were low 14's at 106-107 mph on a 85 degree summer day. MPH shows good potential as my car was only running 105 mph, but 12.50's.

I can't believe this topic has went 9 pages, so far. Replies like, it's a big car, it's heavy, it's may have only been a computer problem, you may not know how to drive. All crap. Coming from guys with fast cars too. Would they be happy if their [Edited by Moparts - Family Friendly Site - Keep it clean] was missing power?

I would have lost interest in it too. I'd put up with peeling paint or rusted doors before I'd put up with 7 mile per hour missing.

Hopefully someone at Dodge gets wind of this thread because as a customer I would not be happy with missing performance either. Whether is be my lawnmower, grinder, minivan or $40,000 SRT8.

What would really put a nice ending to this long winded thread would be some "ON PAR" numbers from your new car!

that LS3 is one ugly pile of junk

My brother is going to buy a Challenger Classic and so is another friend of mine. The Challengers are killer looking and so are the Camaros. I went with Ron to pick up that bad boy Camaro. Its NICE!! Im jealous! If I was in the position to purchase one of the two, it would be a very very very hard decision for me. I was a little dissapointed in Rons Challengers performance and I to would have been ticked off about its lack of performance. Im glad Ron has put himself in a position to do what he did and cut his losses instead of putting up with a bad thing for many years. There were a few Camaros at the dealer that Ron picked his up at and I got to say ,there was a silver one with black stripes that would tempt me to the dark side. But I dont know; the Black Challenger Classic with 6 speed and Trak Pak might persuade me to stick with the Mopar. Black, with matte black R/T stripes, and then the over the counter T/A hood also matte black would be KILLER!!! The Challenger needs to be lowered like an inch also.

auto's are ~400 HP, manuals are 426...
