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.

I was a little hesitant to remove My Ecu and send it Z1. My car is bone stock other then k&n drop in filters They assured me I would notice A power difference even with a stock car. Extremely happy! I know there is a huge difference In the power band all the way through. Thanks Russ and everyone At Z1!

I wasn't sure what the results would be but, dang! It's a new car now. I have all the breather mods and the car is so smooth now. The car has more power all the way up, and the turn around time was only 3 days!!!! Very impressed. I can definitely recommend this for a quick tune.
