I need to get new injectors and was thinking about getting 20%-30% reason being I don't think I want to build the engine. What are your guys thoughts and experience with these sizes. Would I have to get my truck returned for the bigger size? What are the pros and cons of doing this? I was planning on getting an airdog also when I do this, What airdog would you guys recommend?

Bigger nozzles = less PW! That's a good thing:thumb: Yes it would need to be retuned. And any AD with both WS and filter are great. Delete your stock filter while your at it.

Is 30% injectors the highest you would do on a stock motor I am planning on doing the trans I just didn't want to get into the motor anytime in the near future.

I have had 15% 30% 45% 70% 80% and 100% injectors. IMOP if you are going to run stock fuel as in cp3 go with stock injectors. IF you are going to add a 10mm pump or dual c's add some injector.

I run 50 over on my 438k stock motor. I'm using the 8 hole motorsport nozzles. They are stock but flow 50 percent more than the oem. I have used 30 overs on it before. I like the 50s that I have now better. Mostly because of some benefits of the nozzle design.
