Hey guys just fitted a forge dump valve which is meant for the 250 however used a reducer to get it to fit the forge t piece, its fitted with the yellow spring which is good for between 15-23 psi. Is it normal for it to dump pressure at 3k revs static? Sorry if I'm sounding like a dunce but just wanted to clarify
Not really, I have a hks on mine and it does the same, as long as it's a sharp dump sound and not a sound that goes on forever I'd see how it behaves.
Got a forge also with a yellow spring that was installed when I was at RS Tuning. All worked well until recently when on occasion rather than dump via the usual pssst sound it tends to well more prrrrt more of a dart noise. Any suggestions from experience should I use the shims or the blue spring. RS said it's running 1.4bar and was working fine for 300 miles so maybe the spring has lost a bit of tension, any thoughts appreciated guys
No idea fella had it fitted so wasn't involved. It had the backing plate fitted and the hose joined to the T price from the dump valve itself, basically all as the instructions online.
has anyone else experienced a moosing noise when lightly backing off the throttle in the higher gears ?
Yes it's because the dump valve isn't giving it's full phish when you let off lightly, that's what I reckon the noise is anyway, happens in all gears if you lightly let off tbh but noticed more in higher gears.
