Hello everyone, this is my first day here so I'm not sure if any of you know about this ECU Upgrade. Superchips.com has an ECU upgrade for 87-91 MX-6/626's, naturally aspirated and turbo cars. The Turbo ECU upgrade gives you +29HP and +45 ft/lbs of torque. This upgrade also gives an extra 5PSI of boost pressure and takes 1.5 seconds off the 0-60 time. On the naturally aspirated models you get +11HP and +16 ft/lbs. of torque. Costs for the Turbo ECU upgrade is $500 U.S. dollars and to me is well worth it, this also comes with a brass bleed valve for your turbo. The NA models ECU upgrade costs $395 U.S. For all you 2nd generation guys: 2.0L gets +11HP and +16 ft/lbs. of torque and 2.5L's get +16HP and +20 ft/lbs. of torque. 2nd Gen. ECUs are also $395 U.S. I have owned a '91 LX for the past 7 years and it is and has been an excellent car, I currently have 177,000 miles on it and it still runs strong. I just purchased a '90 GT with 98,000 miles on it for $600, it's hit in the front, no biggie, I work at a body shop. I'm seriously considering turning this GT car into a racer. So if anyone out there has any suggestions for me on what to do with the car feel free to let me know. I'll post pics of my GT and LX as soon as I get these pics developed and scanned.
