just a quick one lads ,just for confirmation,going to be fitting sps mani and speedvisions hybrid and new exhaust of dave in the next few weeks,hoping to see 200bhp or over ,at a bar,have all supporting mods including jam ecu ,should i upgrade the fuel pump ,before i up the power,going to reset jam ecu ,when i fit all mods and run the car at .85 ,and take it handy for a couple of weeks till the jam ecu self learns to the new mods ,then up the power and get it dynoed ,and get fueling checked,should i change the fuel filter aswell ,only changed around 6 months ago

You don't need to uprate as the std fuel pump is fine, but that fuel pump could've been on your car since 1994 (or whenever your car was made) so if you can, you might as well replace it with a new one! Not going to do any harm. A bit of piece of mind too!

And as for fuel filter, if you only changed it 6 months ago I wouldn't bother personally! I need to change mine tbh :(

I would change the pump.
You have to remember that its probaly been in there scince the car was built.
Better safe than sorry.

Filter will be fine.

Wideband testing says otherwise buddy.

new stock fuel pump and an uprated fuel pump on the same setup should give the same fuelling as its controlled by the fpr.

if you compared it to an old fuel pump i can see that having an effect as it probably struggles to keep the flow at higher boost/rpm

I personally would go with the Walbro, i did with mine.

But from what Jay has stated, it seems the oposite.
But i cant think how, as its the FPR that controls it, BUT you cant beat first hand experiance.
