Well finally got my injectors installed today, truck runs good, only problem I had is they sent me 2 number 4 crossover tubes and no number 5, but sent injectors direct some pics and they have a number 5 in the mail, They were pretty nice about it, returned my phone call promptly, and apologized, I had to reuse the old one as I'm headed to Louisiana in the morning for the floods , I'll change it when I get back, sounds like great people and polite, .
