does anyone know where you can get a larger throttle body for a I6 i am sure there was a guy buying up stock ones a modding them on here a while ago? is he still doing them? and how much?

Do you want to put the larger TB on the Duel Fuel GLi you have or another car?

on the duel fuel car but it a has a full injected system so no gas ring

Fast XR was doing them at one stage, not sure if he still is. What other work is done to your car other than Gas injection?

wade 1736 cam i think the one before 977B
pacemaker extractors with a high flow and 2.5 straight through fully balanced mild port work harden valves 60tho over 10:1 comp adj cam gear K&N filter chip torque piggyback matchported Manual custom 3.08 LSD diff KYB AGX adj shocks on 50mm lowered lovel springs got it up to 146.3rwkw 98oc but the chip is running 4* retard so i am loosing a bit and the fuel is rich 130.6rwkw Gas but till i get the chip remapped i wont get much more i thought now i would go a bigger throttle body and injectors get a bit more out of it now i dont hav a gas ring and upgrading the intake pipe |

You're just going reduce your engines responsiveness and power down low and chances are with the little power you're already making you wont actually gain anything up top either.
My EF 4L made 183rwkw with the stock T/B and there are plenty of V8's out there hitting 200RWKW before they even think of moving from the 65mm T/B up to the 75mm T/B

A while ago, someone on Fordmods has posted before and after dynoplots when upsizing his throttle body. It showed basically no difference at all (at WOT) below 5000rpm, but power does continue climbing above that where the stock throttle body starts to limit flow and power. So it gives a higher peak HP and at a higher RPM, but no difference in peak torque. You would typically get less throttle response at part throttle because of the bigger throttle bore and resulting lower velocity.

That is where dual throttle bodies are practical.
On a solenoid switch so a second, smaller throttle body opens with the primary when revs reach say 4500rpm

Cam, head work, exhaust and when that's not enough - boost!

righto so moving off the T/B what else is proven way to get a lil more out of the i6? waggin what was your setup in your falcon different to mine other then a bigger cam? turbo isnt on the cards at the moment, i would like to squeeze as much out of what i got first

Everything that you need to make a NA 4L go fast is useless in turbo land. Choose one and stick with it - else you'll waste a lot of money. My EF 4L just had heads, cam, extractors and a tune. Stock intake (no fancy piping, pods or T/B upgrades), stock injectors. Ask anyone how much they've spent to get a "fast" 4L N/A then look at what Snort and Raptor offer

i did have the idea of going turbo but its was well before i got the gas injection but after building the new motor and many $$$ later a dyno run told me that the gas system i had wasnt goin to cut it so thats where the injection came in now if i had of done it the other way around i would be boosting all over town

Yeah, you're limited to how well that gas system will perform unforuntately.
Assuming economy is the highest priority, just make sure you do everything you can to increase the cars performance in your every day driving condtions - which if its anything like mines simply idle to 2500rpm while sitting in traffic and the occasional traffic light drag. Lots of low down torque is the key - forget the peak RWKW figures unless you're going to compete in dyno comps.
