Giving an appetiser like that and then not following it up seems pretty typical for 911 & Porsche World.

30 hp from a chip alone? From 231 to 261 bhp? No chance!

The 3.2s had the first engine management computer on road going 911s. It was new technology and Porsche was a little conservative, but they didn't leave that much on the table.

Geof at AMD can prbably get you 10 bhp, with before and after measurement. I can't remember what conversion factor he uses but I think it's 16%. If he can't produce more than about 25 hp utilising hot film kits, bored throttle bodies, JR air filters with his skill and experience I can't believe 30 from a chip change.

That being said I have seen wild claims that also involved raising the rev limit to 7700!!! This was combined with MAF and was said to be an easy diy bolt on, in fairness to the tuner it was made very clear that it was not intended for standard road engines.
