I asked this question well over a year ago back on a forum that I'll leave unnamed... - it was probably a bit premature so I'd like to ask again now...

Anyone have any experience with a Powerchip on the new valvetronic V8 engines (4.4 or 4.8) from this source? http://www.powerchipgroup.com/

If so, please share your experiences!

Thanks!
