Bought an o8' tahoe, wondering about downloadable tunes, E85

[Travismc]

Hey guys, I just bought an 08 tahoe, and I'm looking to buy a predator...I was wondering, is there anywhere where I can download custom tunes for a 08' tahoe? what about .bin files for hptuners off of ls1tech? If not, can I use the datalogging feature of the predator to log data, email that file to a tuner, and have him make a custom tune for me? suggestions?

what kind of power gains can I see from a stock tahoe? what if I add a volant or k&n CAI kit?

After I tune with the predator, can I still burn E85? I know I'll lose power, but can I? Will it hurt anything?

do I need a new custom tune everytime I upgrade something? Exhaust? headers? MAS?

I assume you can download tunes from the internet and send em to the predator via serial/usb, right? then use the pred to upload via obdII, right? am I confused?

We do not yet have a Predator for the 08 GM trucks, but will soon.
Once the Predator is available, you will be able to get a custom tune from any of our CMR dealers.
You would really only need a custom tune for mods like a cam or long tube headers.

Thanks
