TRIFECTA presents: Chevrolet Equinox 2.0L Turbo Performance Calibration in TRIFECTA Performance - Performance Tuning, Engine Calibration Posted December 1, 2019 3 hours ago, Ericn said: Why do the hp and torque graphs show reduced performance (versus factory) below about 35 mph? Hi, Performance is actually not reduced versus stock under 35mph. The dyno is only one way to measure performance, and it can be inaccurate at lower loads depending how throttle was applied after starting the "run". If you check out the Reviews section of our Equinox product page, I think you'll see our Equinox customers all generally agree it is anything but under-powered from low rpm. 3 hours ago, Ericn said: I was under the impression that I could re-flash the stock profile any time I wanted. I would re-flash it if it had to go to the dealership for 'warranty' work. I thought I read that your system did not add to the flash write counter so it would be very difficult for the dealer to know it had been tuned previously. Yes, you can flash the ECM back to stock at any time. See above for our comments on warranty.
