bought 6pc 42# 440cc injector's from eBay. had terrible time trying to tune my custom built turbo engine platform. replaced these
new eBay injectors with genuine Bosch ones and instantly my problems with idle and tuning were gone. Friend allowed me to flow check these before they went in the garbage. $70 wasted, don't be fooled. eBay(cheap) injectors are junk!.
