Got codes to flip.. Dealer has had car Untuned. for 4 days no luck finding anything.
Thanks.

Plug int the tuner with it stock. Switch setting there .. I sometimes had this issues with my charger but realized that at WOT the car wont shift exactly at the specified point but up to 600rom past the shift point.

Extremely noticable in first gear becasue it going thru the RPMS so fast. Rasied ...

First I will start off with my problem.
My 06 Charger R/t Daytona has been Throwing codes U1121, u0121,p0645, and p0481.

Since I Unistalled the tune and went back to stock. I cant for the love of god recreated the codes.
Does Diablo when rewriting back to stock erased all codes in system?

Could ...

SO its pointless to buy a catback exhuast? that what your saying..

Here is my Datalog from today. Temp is a humid 79degrees it rained early today so not ideal conditions.

i would love to agree with you... But Chrylser spent tons of money on R&D on the suitcase exhaust and eliminating it would have to have some kind of effect whether it be negative or positive. I am not the only one who felt like its a Negative effect.

ALso i have never seen more then a split second of.50 or .05 stKNK retard mainly during shifts so no knocking.

My Best consistent ET is a 14.051-14.200 Very consistent range.

I am from Maryland and drag race @ Mason dixon Dragway and Capital Raceway.

Your statement says Exhaust mods dont need CMR.... but does the Brylcreem exhaust mod change the characteristics of the Compression and exhaust backpressure ...

****DATALOG ADDED******
Hey Guys I have a bunch of Questions.
I have an 06 Daytona With the folowing mods that i know of..
(yeah i said that i know of since i am 2nd owner)
Brylcreem Exhaust, Mopar CAI w/ Steel Mesh Filter, 170 Tstat.

My brothers car is a 06 CHarger RT with added Daytona Exhuast ...

I have them E3's i cant honestly say they made a difference except in COnstant spark reliability which is unmeasurable.

It felt better but that means nothing since my times as of latley havent reflected gains.

Yes, the LTFT has to build back up. It gets cleared every time you flash a tune. Johan confirmed that the Long Term Fuel Trim is used at Wide Open Throttle if the correction is positive. I noticed this with my Ram when I borrowed my cousin's wide band. I ran it with the 93 tune with a mature LTFT ...

Poor quality fuel would cause this as well.
I dont know. i should have had too much octane. Would that have had negative performance effects. Here is what i did.

4 gallons of 93 Shell V-power, drove 20 miles to track without engaging MDS
Added at the track 2 gallons of unleaded 104 oct race Gas ...

Ok with my DA corrected times. I should have ran
Stock and Mildly Modified Naturally Aspirated Engines
13.621 @ 100.422 MPH
Which is the range i was expecting.

And that day i ran my best times was at a extremely low humid day and @ capitol Raceway.

WHen I first got my charger I ran 14.7's Week 1
after learning the car. I I got it down to a 14.05 BEST with 14.3 consistently

After installing the 93 CAI tune and keeping all other parameters the same.
IT ran 1 time a IT ran 14.2 at best and consistent 14.4's thruout almost 20 runs on sunday ...

PLus its abou to get hot soon. so 170 might be good
