Are they all what they're cracked up to be?
At the moment my car, even in second gear, will judder a little if you suddenly stomp on the gas. Im not sure if this is normal in a small engine but it didnt used to do that in my old car :confused:
So would one of those FSE Power Boost Valves solve this and add better throttle response like theyre supposed to?

thanks,
chris.

They work, but you need to know how to set them up otherwise you would just mess the fuelling up. They dont simply bolt on and get instant BHP.

You would notice a better difference if you had other mods. Such as an uprated cam, induction kit etc, then you can alter the fuelling to get the best performance out of those mods.

You can bog down the car easily when you stomp on the throttle, my car will actually stall if u stamp on gas and back off quickly. fuel filter is a good call mine needs to be done as its so clogged up im gettin fuel starvation :eek:

when i say stomp i dont mean litterally, i mean gradually press down to full throttle. its ok untill about half way when it starts to judder :confused:
well i'll replace the fuel filter anyway and update when i have.

Air Flow Meter, tells the ECU how much air has been sucked in, common fault on corsas, it just after the airbox.

i dont have an AFM :laugh:
but another thing to check is the HT leads. my car was doing the stuttering thing at one point, changed the leads and all was fine. also check the rotar arm and distributor ;)

its got DIS packs (Distributorless Ignition System) so there are no HT leads. Is there any way to check the air flow/mass meter?
