3rd for skipping LDS. Personally I've had the same experiences as listed above as well as seen their quality dropoff first hand locally. With where I live they are the "go to" as they're local. More and more guys have been getting left holding a bill for injectors, issues being blamed on tuning when the largest names in tuning (at the time) tried to tune them, injectors (multiple sets) leaking/failing at low mileage etc.
For those reasons my shop won't touch their products, that's both installation or recommending them.
