No 'mechanic in a can' can get deposits out of the filter basket. They may help clean the nozzle itself, but to restore flow in an injector, you must rebuild and replace the filter baskets.
My injectors improved from an amazing 2% spread to a .8% spread by rebuilding and professionally cleaning. This is great for power and efficiency.
Fuel Injection Enterprises did mine, and the owner (Chris) and I were theorizing why my SSEi injectors looked so good for the miles they had on them. The only thing we can come up with is the Toluene I run occasionally in the summer.
