987 v 986 Air box

[The Radium King]

I guess an 04 anniversary edition tune wouldn't work as it's a 7.8 dme. still, a 996 tune *might* work - afr's would be fine, maf readings would be fine with a cayman maf housing. I think it would just be a question of the maps being able to deal with the fact that the rpms wouldn't correlate to the amount of air (3.2 vs 3.4 displacement) but I think that there must be enough room in the maps for this, otherwise lne wouldn't be able to say that a 3.6 bore works fine with the oem 3.2 tune (same thing only in reverse).

so, we need someone with a 3.2 to put a cayman airbox and maf housing in their car and push a 3.4 996 tune onto it and see if it runs ...

That is my most recent plan for my car...though it is not a 3.2 anymore. We tried some updated tunes awhile back to no avail. Currently running an updated stock tune which is better than it was, just not great. Having the car on the road for over a year now, and dealing with various issues from the beginning I'm ready to once again try and make it right. Looking at putting the IPD plenum and a 987 TB on it too.

Will report back once the 996 tune is tried.

I think it would run ok just possibly a little too much cam too early due to the 996 timing. I would have to compare the cam timing differences.
