Hey just wanted to post a good response for once..ended up getting rough countrys calibrator...it completely solved my stabilitrak problem everything is perfect now. Rough countrys tuner doesnt just fix the speedo..it recalibrates the ebcm and transmission to fix your shift points and the stabilitrak system for proper engagement..again I'm a mechanic..triple checked everything..reset all sensors and it was the tuner that solved it..no other tuner recalibrates the ebcm just fixes speedo.
Anyone with the same problem after a lift and has already checked the sensors and wires..get the rough country tuner it will solve it!!
