I'll try to break this down the best i can.
Spartan is pretty pricey, tuner alone is around 1300 bucks, without the 275 or 310 tune. A buddy of mine just got a package deal with intake, dual exhaust with tips, and a spartan tuner w/275 tune, and it was 2300 bucks i beleive.
The part where your not comparing just tuners anymore is when we talk about the livewire compared to the dashdaq, The dashdaq is much better than the livewire as far as guages goes, BUT the livewire will work for you, how long? I dunno, most people run analog gauges to go with, so if you add that to the price you are closer to the spartan price without the 275 tune.
Both tuners are very good, eric has his tuning dialed, I am actually in the process of getting a livewire to try out erics tunes for myself.
