Backward speed fix?

[meddle2k]

I'm looking for a backward walk speed fix that makes it equal to consoles, I see that the world record player "Chris Voltage " is using this fix for his survival map records on his redacted client. Does anybody here know how or where I can apply this fix for my game also? Been looking for a few days now, any help would be awesome, thanks.
