why is drive by wire jettisoned for LS swaps?

If anyone can direct me to some info on why swappers don't want to keep drive by wire from the new engines they're swapping I'd appreciate it. In some cases, LS engines, there are older cable systems that can easily swap in. My suspicion is newer motors won't have that option. And if DBW is good for the factory, why not us? Appreciate what the major negatives are in not keeping the DBW.

Thx for your thoughts.

Having tuned and installed big and modded LS-x motors I have to say I prefer drive by cable.

The drive by servo systems are difficult to get good idle manners from on large cams. This is due to the throttle being the Idle air control.

The major trait that bugs me is that you go to all the effort to build a snappy & responsive motor and the servor is slow on whipping the throttle open.

As much as I like computers I prefer to have my foot run the motor. My foot does not require interpritation.

Ok...but if you're totally content w/a stock cam and are just concerned w/ease of installation, which is easier? Not knowing anything, I was assuming that folks were jettisoning the DBW for ease of installation not drivability. If that is not correct I'd like to understand. If it is (that DBW install is harder), I'm hoping to find some info why. Is it just getting a place to mount the floor pedal assembly or what?

But thanks for posts so far!
