From GotTheBenz:
This thread invites ONLY those in-the-know, NOT those who
has no clue, opinions or slander, to give us their results and proof
of their Speedriven Stage 2 and Stage 3 mods.
I posted this new thread to get facts. And yes, I've emailed Marcin
twice, left a phone message once---with no replies. So here I am:
Please share, and silence to me means "something" also.
Thank you,
