I did EVP-CS tuner for my ride. When we did the first set up it didn’t want to take the program. I still went out and did some rides . Found out that my buggy had a 24 general main mcu after they hooked on line. Pulled it out and sent to them . They re programmed the main and sent it back. Froadn Fab reinstalled it and the first ride was awesome. Like 10 HP gain. She had great grunt and punch in lower rpm. And much better upper performance in and out of corners …
