Pre-Steve W. dyno results
 

I took my 87 911 to visit the dyno for the first time today - in order to have Steve burn a chip for me. 1st run was 206.87 at he wheels and the 4th(best) was 212.29. Torque was 191.86 and 195.87. The car has a Authority MAF with a cat bypass (schnell) and at MK 1/1 muffler. I thought this was pretty good for a motor that has never been cracked open. What have others seen? Will post charts once I download the software.

looks pretty good already

I have a similar set up except with a stock muffler. I might have to try the MK muffler since it looks like there HP there too. Here are my dynos with AutoT chip and after Steve W chip.

Steve modified the chip after this run and was able to get some more power out of it. 208 to 213 but better fuel curve.
My last dyno chart is in this thread.

Nice results Mo !

Where'd you go & roughly how much is it? I've been thinking about having mine done, not to impress anyone for sure, but just so I know.

Precision Automotive in Beavercreek - schedule it some day you have to be at the base. $75 for an hour.
