cars running full goose, filter and bov. got all the bits comin for 1+bar v.soon and have recently fitted a defi boost gauge. now, i have been noticing that on flooring it, the boost firsts spikes up to 0.9-1.1! bar and then settles around 0.8. Just wondering what peoples thoughts are on this!!- whats the norm here? i no the defi's are the nuts and very accurate
theres no bleed valve etc and all looks stock!
Mattygti-r remarked on how un-laggy and quick it was before i fitted
the defi's when we went out for a blast

so..what ya weckon?

standard boost seems to fluctuate according to ambient tempreture but a decatted R will boost a bit higher than one fitted with a cat iirc

did you check all your hoses for leaks? including he restictor pipe that runs from the turbo actuator to the plenum :wink:

the actuators std iteam which iirc is a not adjustable iteam. once the avc-r goes on etc, i go from there- hopefuly it will settle it down!
