Well, I'm the guy with the 11 holes for sale...
I'll be the first to admit I'm not an Industrial Injection fan or promoter. Between customer service and prices I'll never buy from them again (turbo's, injectors, anything).
As you can tell by searching on this forum, there aren't many people that speak highly of I.I. They do piece together some nice turbo's, however you definately pay for it with a steep price and if you ever need any warranty help or a rebuild done, you better go elsewhere...
With that said, I can honestly say I picked up a very decent amount of hp going from Mach 6's to these injectors. They ran great in my truck and pulled very well. You get to a point with a VP truck that you just can't get anymore fuel out of the pump... (so I went the ppump route)
If you were looking at buying new I'd recommend not to as they are overpriced, however my used ones are like new and half the price.
It's your decision...
C.Smith, you are the first I've read about to blow the tip of an 11 hole. The last member on here to talk about breaking an injector was on a 7 hole.
