Howdy, I recently purchased 88 M6 with a Autothority Performance Chip. I tried to call the company In an effort to find out the specs but they do not return calls/e-mails. I found the chip advertised on E-bay. The spec on the E-bay advertisement states 18HP gain. Turner still makes a chip that advertises 43HP, 21 torque. I do not believe that Dinan still has a chip. My question is does anyone know what the advertised HP gain on the Autothority chip and where it suppose to show up in the RPM range ? Is the Turner chip a good product ?
