Please Help Guys.

My Fiesta RST was running on beige 701's when i bought it um the fuel pressure was running at 2.8 bar and it was running pretty lean, so i bought a FSE power boost valve so i could up the Pressure to 3.8bar,

I fitted it so the nozzle coming out the side, marked high pressure goes to were the original Webber FPR goes using a fuel rail adaptor, and the low pressure nozzle pointing downwords on the fuel return where the standard webber FPR connected to is this correct since the car seems to be running really lean now, any of you guys got any ideas on how u install these and how to adjust them probally to a FRST on beige spec cheers BAZ

What even with a car running around 190hp on 701's with 195chip etc, i was told they need to be ran around 3.8

Take the FSE piece of shit off your car before you blow it up or pay through
the nose for it drinking too much fuel.



Get it set up/checked by a professional unless you feel the need for a rebuild.

The cars been running too lean thats why i got it woodford garage in totnes a cosworth specialist who's been working on the car told me i needed a uprated one since the standard webber one won't go much over 3bar and i need about 3.8 for beiges, they are gonna set it up for me then its of for live mapping, i've adjusted it myself and it seems to be a hell of a lot better now not much diff from the standard one but thiers still a load of adjustment left so i'll get woodford to set it up so its running correct pressure / co2 etc.
