I'm looking to upgrade my injectors from mach 3's to mach 5's but I'm hearing there still of a old design.I hear the 4's are a new design and it seems everyone likes them.The only thing is I want this to be my last set I have to buy so I don't want to be left wanting more.(as if ) I just want to make sure the 5's won't smoke like a pig and I won't lose drivability.I don't daily drive truck but I do take it on holidays.I think I'd probobaly keep my 3's till I see how the 5's are.I wander if the 5's are going to be redesigned anytime soon.Thanks Mark..........

 

what size turbo are you running? what other modification have you done?

 

Hey Bob,I'm running the B1-2 and it seems to keep the 3's under control..Thanks Mark........
