Stand Alone?
UTEC is better than a piggy back and better than a standlone.
The UTEC lets the stock ecu handle all the things like cold start, warm start, AC and idle. It then takes over to control fuel, timing and boost when needed.
The UTEC directly controls the injectors and timing so you always get 100% repeatable power. Other piggy back systems rely on fooling the ecu which can lead to unpredicatable results.
The issue with a standlone is that you have to tune it to understand cold start, warm start, idle and things like that before you can use your car in a daily drive fashion.
I like the UTEC, it's the best of both worlds
