I sent out a set of injectors, from my 90 b230 to Cruzin Performance (cruzinperformance.com), to be cleaned, tested, flowed, and refurbished.
Check out the before and after test results Rich (owner) sent me. The preliminary results show uneven flow, pattern, and more.
The after service results show four injectors very close in performance.
The set of injectors I sent him were from a car that was running great, seemed to perform fine, and got good gas milage. Notice the difference in the before and after numbers, spray pattern, etc.
The total was $57 (with return shipping to my door). HIGHLY RECCOMENDED.
Numbers after each test are for individual injectors.
