What size injector nozzles were in that truck that you just mentioned and it had to have some kind of an extra tune also didn't it? Would you still get o.k mileage with your injector nozzles if you keep the foot from hitting the floor? Isn't there a 7 hole spray in the stock nozzles? 10 hole has got to be nice. Thank's
Thank's. The part in your signature says 129% nozzles and wasn't sure how much of a nozzle you had or if you actually do have a 129% nozzle dumping it into the cylinder.
Are the 120hp nozzles on your website the ones you were talking about or something else?

No, in that test was just the 129% nozzles ==> 29% flow ~ 90 HP without any changes on fuel map.

So on the website the 90hp nozzles are the 129%? How do the 120hp ones do?
Thank's MDE
