installing my nano setup,
INSTALLED AEROMOTIVE 340
piggy backed the nano onto my bottle
bought br7ef plugs for ngk
now i need to pill up for my fuel jets i think

right now im pilled for a 150 shot through a nitrous outlet plate, but since i bought a baller aeromotive 340 fuel pump , do i need to up my fuel jets still before i go for a retune? sicne its a much stronger pump

I would go with the base jetting that NO recommends for starters and tune from there based on reading the plugs and AFR.

going to do a dyno tune, so plug checking will be a must.



im going by this chart

however, idk what the bigger fuel pump does to this chart, if anything

Those charts are based on your engine having adequate fuel flow/ volume. That pump should be plenty. You will be fine starting with the base jetting and tuning from there.

I would still go with the nano jetting. The nano getting is taking into account that the pressure is not dropping. The pump has nothing to do with the jetting.

Fuel pumps do not...I repeat DO NOT supply "pressure"...they supply volume...the restriction in the regulator provides the pressure.

For example...hold a garden hose with the faucet on full (volume)...then place your thumb over the end (restriction adding pressure)...when you start to see fuel pressure drop under load is because the engine is using the fuel faster than the pump can replace it...this is a volume issue and why the pump needs to be upgraded.

Pressure and volume are too interrelated for this over simplified sentence... to me it sends the wrong message.

how does it send the wrong message....yes it is simplified...but pumps still do not supply pressure....upgrading the fuel pump does not increase fuel rail pressure, but it will fix a low fuel pressure under WOT due to the pump not moving enough VOLUME to maintain pressure

went with a 36 jet for the fuel

Glad to hear that you got that finished up. If you have any other questions let me know
