HPP or HP?siemens injectors arent top of the line, what they sold you is a Bosh Gen 2 injector. if you want top of the line look into Injector dynamics or one of the other companies that makes billet injectors. but yeah those guys are jack asses, reminds me of the hassles with HPP trying to get them to correct their mistakes
I've heard a ton of bad about HP but not so much about HPP
