Review on 💪 Hyundai Tiburon Performance Chip/Power Programmer - Boost Fuel Efficiency, Save on Gas & Enhance MPG, Amplify Horsepower & Torque! by Jon Smith

We bought it a year ago and just installed it a month ago. I found it a little awkward to put on because I'm a bit mechanically inclined but know very little about wiring. This is for my son's car so thought I'd wear it while he was in college. The manual didn't list the cables used for the Hyundai so I emailed them around 5am on Sunday morning. the day before I received the reply. It was the hour. Not only did they tell me what wires to use, they included pictures. I disconnected the battery and installed it in about 10 minutes. I let it sit for 10 hours before connecting the battery. I immediately felt a significant increase in performance. However, after two days the consumption dropped and I noticed that it was rough when idling. After a few minutes of inspection, I noticed that one of the new wires was loose on the new connectors. So I unhooked the battery again, reconnected the wires and sealed them with electrical tape to the end. I let it sit for 24 hours before plugging it back in. Now this thing runs fast and I've got over 150 miles on one tank of gas. . My son was over the moon when he came back from college and rode it. I park my team, can diesel and drive his car for a week. Now it's fun to run at 5th speed.
