On my 08 type s would adding bigger injectors add more power if I already have a kpro ,intake ,lightened flywheel ,and erg delete. And if so what size . Thanks. Im just trying to get more power without turbos or supercharger.

 

I mean ktunner not k pro

 

I doubt it, you may want to invest in pre-cat deletes and some other mods with the K-Tuner. There's also the bigger intake manifold and throttle body; but beware that you are going to spend close a lot of money for not that much HP gain. The largest gain's are from the pre-cat deletes and J-Pipe replacement.

 

Nope it will had no power at all. On my previous TL I had full bolt ons and still didn't crack 300whp. Injectors are needed when you run out of fuel.
