power boost valve
 

are these power boost valves any good?

In a word...No. (If Im correct in assuming you mean the variable resistor things you can buy off ebay)

are you on about the f.s.e power boost valves or the cheapy 20 bhp resistor pieces of sh*t ? lol !

No you on about the ebay "chips"

The FSE Power Boost Valve replaces the standard fuel pressure regulator fitted to the engine. On acceleration the Power Boost Valve will increase the fuel pressure in the fuel rail at 1.7 times the standard rate. This enriches the mixture under acceleration which will improve the driveability of your vehicle.

Ahh I stand corrected then! lol

sorry to hijack, :oops: where can you buy these boost valves?

you can get them from demon tweeks or maybe motorworld or halfords otherwise a good car shop

I've got 2 power boost valves 1 second hand an 1 brand new in box never been fitted pm me

sorry to hijack but how hard are they to fit?

It replaces the fuel pressure regulator mate! but all it does is enrich the mixture under acceleration, he won't feel and gains and he will have to top up on petrol a little more often. tbh there is no need to adjust fuel pressure unless your planning on camming mate imo!

even then a remap would be a better solution...

no -they don,t work ,on a modern car,presuming it is running ok at present -used to work on old ecus, -buts that ten years ago,std ecu corrects fuel so quick that any accel enrichment will be very qucikly tuned out by ecu- so no save your money .
a remap will not work -to do this ,and if its a 3 plug ecu ,very little if any gains will be got -on std car- remap when you have changed engine config
