Actually I did have the seat belt on. I never drive without it. There was a problem with the sensor which seemed to be a manufacturer defect. I took the car to our dealer here which then the problem was solved.

That's good. 👍 I don't know why people still drive without a seat belt.

Be safe.

Re: 0-60 times for the 5.7 WK2 - Post them here

Attached are three pictures where I tested yesterday through iOBD2 software from iPad. For the 7.837s, during that the temperature was 38C (100.4F). I have only one mod and that's Mopar Intake (installed very recently), and nothing else.

The other two were runs @ 35C (95F).


During winter here when the temperature was below 20C, I used to get slightly below 7s (around 6.9 something) and that was without the Mopar Intake. I will test it with Mopar intake during next winter when temperatures drop below 20C. I should be making less than 6.9. I remmember last year during summer without the Mopar Intake at the same temperatures I would make around 8.1-8.2s. So it looks like the intake is doing some work.

The heat here really kills an engine's performance.

2012 Summit 4x2

AFE intake, dynomax cat back, Diablo Trinity 93 tune
22x10 rear wheels with 305/40 tires (1" larger than stock)
Air temp 85F and I forgot to turn the A/C off
It surprised me that it will now actually spin these big wheels and tires with the traction control off.

Re: 0-60 times for the 5.7 WK2 - Post them here

Just curious, I have a "70th Anniversary" Laredo 4x4 w/ Hemi. The build sheet shows I have a 3.45 Rear Axle Ratio. Is that the standard "stock" ratio? I ask, because that 3.45 is listed under the "optional" part of my window sticker. I don't see an axle ratio listed under the "standard equipment" part. That could affect the 0-60 times no doubt.

That is fast considering the weather conditions!!

I just purchase the Diablo Trinity from amazon and will use it once it arrives. But I will tune on 91 octane since we only got here 92 octane fuel. I will post stock and tuned results.
