5 of 5 G37 Mail in Re-Flash March 22, 2024
Reviewer: Wyatt from Prescott, AZ United States  
Turn around time was fantastic. My ECU was shipped back within 24 hours of it being received. Driveability has definitely improved, especially throttle response. I’m noticing it pulls a bit better in lower to mid rpm’s now as well. It also doesn’t hurt that my MPG has improved. I wish I would’ve done a reflash sooner!
