Totally worth it for budget builds. I'm always on call and never know when I'll have a day off to spend at the tuners so this was perfect for me. It is a night and day difference! I have all breather mods/bolt ons and was running lean but now there is no hesitation, it pulls hard from every gear, no idle dips or CEL's. Best if all was I sent it out and got it back in 6 days, super quick turnaround. 5 stars
I was slightly skeptical about this reflash at first but decided I'd give it a try. It was a night and day difference for my car with some simple mods. Everything about the car feels better and faster now. Don't get me wrong I loved driving the car before but now that Z1 did their magic on it, it is a blast to drive. The team at Z1 was also very helpful as they explained what they do with these and what you get out of them. 10/10 stars on this reflash. It exceeded expectations for sure.
