I've had two diff kinds of SCT chips in two diff 95 GT's. The first wasn't even tuned for my car, I had an issue with the ECU not the chip. When I bought my car I didn't run quite right, previous owner had the timing turned up via the dist plus the chip, the chip has a selector and can hold 7 tunes, it uses position 1-3, when I bought it it was running on 5,6,7. I reinstalled it with the dist set right and batt disconnected and now it will not start or run on 4-7. Point is a lot of issues we hear or read about are usually due to human error during use or install.
Edit: just for clarity I had ECU woes way before the chip in the first car.
