    Temp/Humidity can add .75 to the "best" time.

    Assuming in all the runs you left it in "D" with the "OD" off it could be a number of factors including a slipping trans.

    Frequently it is more than just one factor.

    Good Luck in figuring it out.

    You definitely need to find the missing horsepower before adding more go fast items.

    I could probably find it. You think that would make a difference?

    Oh yeah. My best stock run was 14.738.
    One of my first ever runs was on a night was about like 90 degrees with 90% humidity. It was absolutely awful, practically swimming it, soaked while standing still. I ran a 16.10 that night.

    You will be able to tell the difference but your car has other issues needing correction. Look on www.pure-gas.org to see what’s available in your area.

    So I brought the tuner inside and got it updated through wifi. Had 127 files to update. Then took it out to the car, de-tuned the car back to stock and then re-loaded Marty's tune with 4:10 gear option. Car feels stronger but that could be in my head.

    Pretty sure all I did after getting the 4:10 installed was just change the axle ratio.

    So I had a 3:55 tune with 4:10 gears. Could this be the difference in six tenths of a second?? I was expecting 14.20's at the track but got 14.80's

    I'll have to take it out to the track again to find out.

    Thanks for all the help.

    There is an issue with the car.

    The car should have picked up at least .2 and the fact that your mph is down is an indication of an issue.

    I needed to spend some time with MIzz MO today - call me tomorrow. You have my number.

    I would be concerned with losing MPH, you need to make sure the car is running right.

    Seems to me that running 4.10s with tune for 3.55s would cause the shifts to be premature at each shift point. Wouldn't that impact the HP curve and the ability to build MPH ?? Just sayin'

    I'd have to dig out my old slips, he stated that the car went 14.70's stock... I find that very hard to believe... 14.90's maybe but not .70's...

    "The Fat Bastid" ran a bone stock time of 14.738 @ 95.37 at Mason-Dixon Dragway on 23 October 2004. Don't think I have seen any better time on a stock Marauder. Cool, dry night on a 2003 MM and a small light driver.

    I think it best that the parties discuss it verbally.
