- The DW injectors up to the 850cc ones use latencies virtually the same as the stock injectors, so they are easy to tune and they idle so nicely (like stock).
- The last set of Five-O injectors we tried to install were not machined and had the wrong o-rings, so they had to be sent back and exchanged. A minor PITA that delayed the customer's install by a few days.

hmm, I agree on o rings that has happened to one of my customers, But more a user error for not specifing what vehicle they were for.
I guess its more of a user preference
