What gains would I see on my HO truck by adding Bosche 300 injectors only?

 

I'm pretty sure that the 300's are really 275's. They used the same injectors in both engines. Should gain you about 40 HP, not sure on torque. Others will chime in, or better yet do a search on the 275 injectors.

 

I think we see about 40 HP. You can definitely feel it but it leaves wanting more for sure.

I hear they're a great combo with an Edge EZ which is what I'll be adding soon.

 

I put in the Bosch RV275 injectors and with the
Van Aaken box I think it's a great combo.You won't
have mega HP , but you will pick-up good power
and more importantly, greatly increase throttle response
and low end power. I think this is the most my stock
clutch can take , but I don't abuse my truck, so other
trucks may slip their clutches with this combo.

 

The 275's and an EZ are a beautiful combo. EGT's stay in check, power is very smooth, and there's no smoke unless you try and make it smoke.
