To any of you who have been down this road, I finished up my install of a 987 air box into my track only boxster and it seems to be running a little rough since getting it all back together. Apx how long does it take the ECU to adjust to the increase in air flow? I can't run it on the street so I only have a few start ups in the shop so far.
For back ground, it has a '99 3.4 from a 996 and the ECU and the MAF are also from the 996
