I approached the guys at EFi at their booth at WBM2017 after frequently reading mentions of their quality and reputation across the larger forums. I explained to them my goals, and they happily advised me what components I needed. I then brought my '12 WRX to them, where I was treated exceptionally well. Any questions or concerns I had were addressed simply and directly; no bull. My parents, who wanted to see the process, even had an awesome conversation with the guys!
This review is far overdue, as the car has been running like a top. The quality of the work and tune is top notch, and customer service is always readily available. All of my emailed questions are quickly addressed. I am extremely satisfied with the experience I had with EFi, and look forward to working with them further. read more
