Default E85 conversion on 04 E46 M3 FS - should I be worried?

A car I am considering for purchase has this kit:

http://www.advancedfueldynamics.com/...or-bmw-e46-m3/

I do not want to keep it for myself ... anything I should be concerned about if I uninstalled? Any potential damage to the engine, rods, rod bearings, etc? I think one of the ways they get more power is by bumping the timing, etc.

so far no long term effect has been noticed since these kits are relatively new. short term wise there seems to be none except most common thing I've seen is on cold days it requires two cranks to get the car started. other than that I haven't seen much negative things about em. I got a kit but haven't installed yet. been busy but I will be installing it soon along w/ new fuel pump, filter and regulator.

Why? I've had this kit for 6 months now and can't imagine not having it.

You should be concerned if the car currently has e85 in it - because without the kit you'll be running suuuuper lean.

Otherwise, no. It's a piggy-back, so if you remove it without damaging anything in the process you're just operating the car normally.
