I need to know what sorta HP gains i can expect with the following mods:

Extractors
ECU upgrade
RPW enlarged throttle body

Have you already got a cat-back exhaust?
I would suggest getting a rising rate fuel pressure regulator to go with the extractors.

yeah i already have a 2.5" cat-back installed with a pod filter...

how would an FPR help?

suposedly extractors can make the fuel run a little rich/lean... or so they say..

yeah extractors can make it run a bit lean (or so they say) and an FPR also helps to overcome flatspots.

...does the FPR itself have any effect on fuel consumption at all?

been thinking about fitting an enlarged throttle body but i don't know if it's worth the money and effort. i'm not exactly crash-hot in NA-tuning, which is why i'm longing for a turbo conversion but as much as i hate to say it - I WANT MORE!!!

Well it definaly does have effect if u just putting a FPR buy it self, u need a piggyback ECU 2 tune it 2 optimize it!

1 good thing is u can adjust the pressure, which mean u can do around 600km -700km 4 long distance, & only do this when u have 100+ ron in your fuel tank! I did it when i was away 4 a trip, i wind down the pressure, & add more ron in my tank, got around 650km with 1/4 tank left!

hmmm... it's not often you find ppl run 100RON fuel on their FTOs lol!!

we can sort out these quarrels on 7th of June night I know you guys are coming

I'm also considering Extractors/Englarged Throttle body/RRFPR/Unichip

I might as well get it all done at once right? But I assume it's best to do in this order if I want to do it in stages?

1. FPR
2. Extractors
3. Throttle body
4. Unichip

kaveman and FTO338, did you guys fit extractors yet?
