fitted HKS blow off valve and now when u dip the clutch when @ high revs the revs drop then instead of stopiing at 1000 revs it drops right down to a few hundred then it rises to a 1000 revs again any ideas?? thanks

Its a well known problem, do a search, but basically, as it vents to atmosphere it changes the air flow to the engine, nothing to worry about but can cause stalling, which can be awkward and embarrassing.

Try adjusting the nut on the back of the dump valve, srew it in IIRC, to increase the tension on the spring, that sometimes helps, if not, HKS do an idle stabilizer, i have never used one, but have heard they sort things out.

Try just part the way, and then more if you need to, TBH (to be honest ) this didn't work on my car but some people on here say this works. IIRC - If I Remember Correctly - must be texting too much

Just seen you have a HKS ECU, which one is that, as someone may be able to map around this

Ralliart ECU won't fix it, i tried this for the same reason, you need a mappable ecu, with a map sensor, but the HKS stabilizer thing does work apparently, I think Makes on here tried one with good results, but as always, i could be wrong

If you got a E7 fq-300 HKS dont do a bov for it only for the standard E7 & that dont always work, i've had a mare with mine got a Forge bov at the mo which is working v well but its a recirculating one.

Can check through all HKS stuff if you go to www.hkseurope.com & they list all the suppliers for the uk as well with numbers etc
