Yep its all about the boost.


If I could pull the same 2.oo 60ft as you Id actually dip into the 14.40s

Repeat question:
How are you launching when equipped with 4wd auto? Are you locking rear end while in auto? Being that Both 4A and locking rear end disengages at higher speed, are you switching back to 2wd and unlock after the launch?
Thanks

2015 3.5 EB with MPT high boost tune only. 4 wheel auto launch.

Ive been back after since, Much cooler air, took the spare tire out and ran the fuel tank almost to empty.. and managed a 13.1.

Cant find the slip.

I know... Proof or get out.

My 2015 King Ranch 5.0 accelerates slower then my 2015 XLT 3.5 EB did. It really doesn't matter to me how fast I get to 60 mph in my truck. I know that much, I get there in comfort.


If I feel like going faster I use the car in my signature.

Very respectable

Are you having any problems with wheel spin in the 2wd? At what RPM are you launching?
Oh, and what is your gear ratio? I'm sure I've read it somewhere in this thread, but I can't remember.

Oh right!!! Ok so, on oem wheels(18s) on 20psi e-locker at about 1200 rpms sway bar unhooked and in manual mode. 3.55 gears with MPT prx 93 tune with 15 bucks of e85 and 5 bucks of 93 lol. Would have to verify actual gallons of fuel mix. And hammered down. Not shifting into 4th gear...

Any update on the 5.0 tuning? Numbers and such?
I've got 4 different tuning companies and would mind taking a look at you guys. But I know the tuner is different. But if it's worth it I'm in.
