has any one got any feedback on FSE boost valve

[lamb jiblets]

I`m thinking of buying a FSE boost valve ,am I wasting my cash?

Dont expect much from just the valve on its own, but when run in conjunction with other modifications (like chip) works well. We do use them here

If you're chipping it you can richen it without messing with the fuel pressure. If you aren't then just dumping more fuel in will typically make the engine safer and perhaps more responsive to the throttle but ultimately less powerful, so no particular reason to do it unless you think the engine is currently running lean at the top end. The FSE regulators have a reputation for giving inconsistent pressure with age, and if true this would be a very strong reason not to use them.
