I run Sams club 93 octane in my truck. I have never put any type of fuel additive in my truck. I run a street chip from JL. 7.996 1/8th mile which is basically a 12.5x. I'm sure I'd be lots quicker with his race program.

 

Your 1/8 mile time is very good,but don't assime or equate that to a 12.5 1/4 until you have the timeslip in hand.Some of these trucks taper off after the 1/8 mile.But your times are great and with a few mods your gonna be right there.One word of advice,and I'm no genius but if you find a chip that works stick with it,some of the guys have a bag of chips .like bags of candy.I found one stuck with it and it has taken every mod I have thrown at it,the brand is unimportant, your satisfaction is the thing that matters.Don't go to the expense of exhaust or a throttle body,I really don't see any changes in power, sounds good but put a converter in for what the throttle body costs.You might wanna get a pro cooler from JL i run both pulleys,small upper,large lower,it runs like a bear and stays cool.Stick with the major tuners they won't laed you astray.
Nice Job

2_Fast4u,
So...it looks like I am the only one running just straight 93 octane?
How much faster would I be with more octane? I don't hear any pinging.

 

Is that on F-1s or E/T Streets?

I always use 93, I have yet to add 100 Octane to her yet.

 

et streets. 1.77 60 ft. With the F1's you'll get a higher trap speed for the 1/4th. If the track is prepared well you are lucky because the local tracks here are not that great.

 

My'01 went 12.78 @107 with only a J/L chip ,J/L 3# pulley and the tailgate down.It was on F1s with 3/4 tank of 93 Sunoco,spare tire ,sway bar,and everything else the thing came with stock!
