Hi,
Recently fitted a blitz ss d/valve to my99 and sounds excellent,had heard of the probs that were related ti vta valves.With the original r/c valve the revs would drop when the lutch was dumped to qiute a low level.But with the new vta they drop to the point of stalling and loosing the pas on some instances forcing me to heel and toe to keep things going.
Even tho this can sometimes be a pain i can live with it due to how lovely the valve sounds,but wondered if there was a screw or valve on the ss blow off to adjust to make sure the spring shuts fully on lift off?
Regards Gene

I have a Blitz SS BOV aswell and I fully adjusted the valve and never got any joy with the problems from the Blitz.

What do yopu mean?you never have had these probs or it didnt cure the probs ive got.How did you adjust the Blitz?
