Ok so this review starts in July of 2020 . I took my sons car to get a supercharger and full exhaust put in a 2020 Toyota GT86. After calling around and reading reviews, I chose this shop. Working with them we decided on sprintex SC and invidia exhaust and headers. All parts were "plug and play" we agreed to do the installation. Because my son was in college I wanted tuned to high octane pump gas as I didn't want my son to run out of gas because he couldn't find E-85 or a racing fuel, plus we explained that this would be a daily driver. After waiting till the end of August we finally got the car back. It was "bucking" within in a week. I took the car back because the engine light was on and found the plugs burned out. Their suggestion was racing plugs, put them in and the car that was already bucking only got worse. When called for help he said he fired the old mechanics for not doing work. And claimed that we wanted E-85. I finally took it( had it towed as it continued to now die) to my home in Kentucky and had a shop, two shops confirm the ECU was not the correct one for the car/tune. When called back to find what ECU/tune was used we were told not to call ever again. We paid over 12 grand and got shafted. Do not use this place for anything. They will destroy your car. Will be getting an attorney after all new bills are in and finalized to try and recoup our losses. read more
