This might be uncharted waters, But has anyone done,seen or heard tuner hp shootouts?

[Beatngu]

There's a sticky thread with tuner pros & cons, but I want to see real
hp & tq numbers by each
even head to head 1/4 mile times

I'm moving to a 6.4 soon and I'm curious on who's the baddest not by opinion only.

Innovative made my 6.0 run the best , considering sticking w/ them

Spartan advertises the most power with there 350 tune but I havnt seen any dyno graphs of it

[08stroker250]

Not sure where the graph is, but the 350 tune made 38 horsepower more on the dyno than the 310. Same dyno. The 350 tune isn't a great track tune though. The 310 seems to be our best race tune. I actually think the 350 would be a great sled pull tune, but I don't know of anyone who has tried it yet.

With our 310 tune, I have ran a 12.81@103.2 in the 1/4 mile with a 1.700 60 foot. I know several others who have ran comparable times.

Is the the 350 just not as fast cause of traction or different shifting? I got traction bars, and run my 13.50 mudders down to about 40psi so getting traction shouldnt be to difficult?

Good info, why might the 350 tune show slower times? What about with the NO2? which tune is faster

I think traction and shifting played a big part in it, but I think some other things need to be tweaked. I think it maintains too much rail pressure.

I just did a small build and ported rails was one of the things I added. I will be going to the track (1/8 mile) the first weekend in March, so we will see what happens. Other mods were H-11 studs, EGR cooler delete, and CFM+ intake elbow. I will also be a good bit lighter when I race. Should be around 7800 lbs by then.

Keep us posted, by chance what did the 310 tune lay down ?
