Running the new spartan 300 tune. So far it's much better than the 275. Smoother shifting, smoother power delivery, and more smoke!!
Does anyone have any dyno #'s on this tune yet?

Its not a race tune, if you want dyno numbers run the 310.

I would guess its not much short of the 310, just a lot more tame. Power does not come on so hard which makes it much more driveable.

and more smoke!!

I actually find that it's the cleanest of the big tunes on my truck.

As for power, I would say 550-570 at the wheels in comparison to 530-550 with the 275 and 570-590 with the 310. These are guesstimates since dyno's read all over the place.

True, my buddy dynoed 539 with the 310 and his track times put him around 610.

I've seen lower than that posted by people. Track times will definitely make a dyno look bad, but all a dyno is good for is a tuning tool anyway. However, I do think there are variables with track times that should be factored into the calculator that don't get factored in. My case proves this big time. :hehe:

I agree. When I dynod it was around 75 degrees and when I was at the track it was in the 50s. That 20 degrees makes a difference!

Does that mean the 250 hp tune is somewhere around 510?

I've seen it dyno in the 515-525 range on a nationally respected dyno.
