I have a Unichip kit, I bought the car a year ago and it never stayed running, So last week I switched it back to Factory ECU and it stayed running, I bought the Unichip already in the car from previous owner. It is a full kit, and has a no boost and a boost tune label on the back. I was wondering if there was a way I could reset the tune so it might work. I have three switches but never knew what they do. Please help.
