fuel injector maintenance

Who's a good guy to send fuel injectors to for cleaning ? I had fuel cell foam disintegrate early in the season and the engine has been down on power. Today i just put new plugs in and checked egt with a temp gun. I see 1 and 2 cyls are down 100degs from 3 and 4. compression is good (190-200) and the engine sounds crisp. I am starting to wonder if 2 injectors could be partially plugged. I replaced the bladder, foam, pump, and both filters after the 1st race of the season. The filter at the pump was full of old foam , maybe some got through? What do you think ? BTW, it's a Toyota Atlantic 1600
