I know some of this post needs to be in drag racing .but just want to share truck had best 60ft I ever had (1.65) .DIDNT hold it for 2 reasons people have stealing my slips from E.T.tower. REASON 2 I had a pair pliers in the dash.when it left the line pliers flew back out of dash and hit me the chest .scared the **** out me.but it ran 8.00 flat at 70mph so you know I let off .......but here ? since I have hp tuners know I was wondering are any of you running 2 tunes regular tune and a meth tune in heat or at track . I don't to spray meth all the time .with meth tune set on kill I don't want my wife driving with meth.i was thinking I would down load regular with meth disconnect .then when I wanted meth power it up and switch tunes....thank Jamie (for helping with tunes)

 

I run the same tune all the time, only change tire size info for track as I run different wheels.

I also don't DD mine so that's a factor.

 

I'm in the same boat as Pat. I have a seperate tube for the track but both run meth. IMO of you're at the point where you need meth then run it. If not then don't.
