    What is the drivetrain Loss? I have always though an automatic would take 15%

    Wow, that's a pretty large swing between the two, has either car had a new flash lately?

    Both cars were flashed on April 13. PCM and TCM on the Challenger, TCM only on the Charger (PCM update did not show up in WiTech due to when the Charger was made).

    Pulls were done in 6th gear as that gear ratio is 1:1. Went up to indicated 197 mph in the car, 198 and 199 for a very brief moment on the dyno's output screen. All pulls were ran in manual mode (shifter in M) and ran to 6250 RPM.

    Dyno sheet shows "CF: SAE Smoothing: 5" .. whatever that means, LOL.

    EDIT: After quick research it seems these are corrected numbers based on the weather conditions, to the most accepted standard, SAE.. rather than STD or uncorrected which would read even higher. Smoothing is just to make the lines (HP/TQ and Air/Fuel) less jagged...

    Wonder if I will get more or less hp on dyno in 6th since they only ran it in 4th and 5th?

    On a Dynojet, you will probably get less running in 6th, with all other factors being the same (SAE vs. STD for example), due to the higher than 1:1 ratios in 4th and 5th. If I remember right, aren't you the one that had your rear brakes fried on the dyno, too? Dyno operator should've known to run in 6th, or at least asked or looked up.

    These runs today for us were done on a Dynojet.

    I
    I will start of by saying nice numbers and nice hellcats both of them are sweet!! But I have had alot of dynos done on my cars.and corrected is always higher then non corrected that I have seen.corrected dynos are corrected to the perfect conditions.sea level, humidity things like that.uncorrected is what it put down at that time.under the conditions at that time.i have only had my hellcat for 5 days but it won't see a dyno u till June 25th then I will see what it puts down.but in the end those are sick numbers anyway u look at it:)
