Another thing to consider is that very soon EFI Live will be releasing DSP5 tuning for the LBZ and LMM trucks. This means EFI Live custom tuning that is also switch on the fly. Vendor/tuners like myself can write you DSP5 tunes with a wide variety of tunes on them including: tow, economy, smoke, and performance tunes from mild (375-400rwhp) and stock transmission safe up to 530+rwhp tunes for guys with a lift pump and built transmission. We can disable the EGR, delete the DPF, correct for tire size, remove the speed limiter, get rid of the hiss at idle that you'll hear once you upgrade your exhaust, and you will never outgrow EFI Live. If you decide 2 years from now you want to build your trans and have more power you let us know and we send out a new tune. 2 years later you decide to upgrade your turbo, again let us know and we send you out a new tune for it.
Can you tell me more about this. When will this on the fly be avalialbe? What all could you set up for me? I would like a towing tune, milage, DD tune like 150 hp and a performance one so I could turn it up once in a while. What kind of $ would it cost. But the big thing is the adjust on the fly option I really like. And like you said couple years down the road if I want something bigger and better I can with EFI Live and don't have to purchase something else.
