I asked the developer. however, he never got back to me. However, I "assume" about 15 HP and about 15 lbs. of torque. At least it feels like at least that much at the low end per the but dyno. I have had the chip for about a year now so my memory for the stock chip has faded.

BTW, I changed my plugs yesterday after 30,000 miles, they all looked light tan and appeared to be running well. I average 22-24 mpg mixed. Interstate 28-30 mpg at about 65-70 mph

here are some dyno figures, power is not calibrated right. torque is though. this is Phil Sanderson's e34. The car is a 12/1988 build 525iA, M20 engine. Interesting the 95 ron tuned chip performed better than the 98 ron tuned chip. Car was running 98 ron all the time. Comments anyone?
