After living with my DinanTronics Sport unit for 2 weeks now and using it exclusively with top-tier 93 octane fuel on Stock, Sport (+2psi) and Sport+ (+3psi) settings, I can say that I am happy with the purchase and can confidently recommend it to others.
The pros are:
- Hardware has good build quality
- It uses 2 sensors instead of just 1
- Install is easy
- Android settings app is not elegant, but it works and includes boost gauge (better than changing settings manually on the hardware)
- Measured on my butt dyno, power gains are noticeable and satisfying
- Driveability is not adversely impacted on the settings I've tried
- Bang for buck is good
The cons are:
- It wasn't cheaper, or free
- It didn't install itself
- I will probably have to remove it every time I bring the car to dealer for service, in order to avoid potential warranty issues
