Looking for advice on replacement injectors. having an engine rebuild done with Weber Performance parts. Went .4 over on bore with new crank, pistons and the works. Heads new with roller rockers, ported intake man, Turbo is replaced with upgrade TA-49. Chipset is the old upgrade Kirban 93. Injectors are old factory psi. Need to replace them. Am interested in keeping current chip but don't want to have issues running lean. Kirban has a 30 psi injector which is a slight upgrade from the factory 28 but is that enough? Not looking to break any track records just want to continue to have fun...
