I guess my standards of a street truck is alot different then others....
I hate having to drive by watching my mirrors to make sure I am not smoking someone out behind me.
I don't know how much difference there are, but I ran 10 holes on my 24v. They were crazy smokey for street driving. I removed them after one trip through Morgantown, W.V. Too many people were telling me that I was #1......using the wrong finger.
Whos 5x.018's? You get that size you should dual feed them. You ever think of putting that money into your injection pump instead of just putting bigger and bigger injectors in. I have ran 6x.016 and 5x.018 dual feeds and never came close to cleaning them up with a Scheid Lightning 2.8 turbo.
