No you don't need a computer, install is simple through the OBDIi, it is tuning and yes hot tunes will produce smoke, but it is not a smoke tune. It's intent is not to produce excess smoke. It smokes because of the excess fuel.

Agreed, autocal is the easiest

Ya but I would just like to have a tune that would produce some smoke and I was gonna get the dsp5 with the 5 tunes, I want stock, smoke/lope, turbo whistle, tow, race and should I get a intake and lift pump?

Yes on both intake and lift pump, Both a good idea. With DSP5 you have a single DSP5 time that is adjustable on the fly with a DSP5 switch or edge insight. You can get multiple DSP5 tunes as you upgrade

Of you did the insight monitor it would serve as your gauges as well

Depending on where you are in Maine there is a good place down in Nashua NH. Or go to one of the on-line suppliers. Especially one that supports DB!

No real need for a lift pump or an intake. The factory intake is good for well over those power levels and a lift pump won't do much for you at those levels either. I doubt you would be running out of fuel with a 100hp tune.

agreed. it has been proven numerous times that the "CAI" are not any better or sometimes worse then the stock filter. i would keep the stock filter. as for the HP, 100 HP is pushing the life on the 5 speed Allison. 60 HP is about the limit for keeping it alive for any length of time.
