update...
I blanked off the breather return and put external breather cap as suggested (that seems like nice place for some NOS in) I checked for any other boost leak, none found.
I also had the battery and charging system checked by an auto electrician, all fine. auto electrician said the cables provided were not heavy enough for 57 amps in any case. each charger is meant to draw 57 amps for a total of 115, it was drawing only 80.

I did four e-ram on and four e-ram off runs on my fave secluded strip allowing 5 mins recharge time between each e-ram on run. the result was a consistent 13.9 secs with it off and 13.8 with it on. this was done with 2 people, full fuel tank and toolbox etc in boot. Eight times straight, no mistake, it does NEARLY NOTHING.

also for the guys who reckon i could have built a true turbo for the same money (dont know how unless i owned HKS or something!) theres 2 reasons i didnt do that. one is that a lot of what i have already put in like exhaust, intake etc would have to come off and would then been a waste of money.
The other reason is im already at about the limit of what power the auto can handle n/a. another 20 kw would be the absolute limit b4 bang!
so i was really chasing better bottom end below 2800 rpm where the car is flat. and i figured that as most turbos have only 2-5 psi at those revs it would be the same thing.

anyway even if i send it back and trust them to refund me, im still about 400$ out of pocket, so i might add better impellors and put 24V instead of 12V thru the thing, then if it burns out, bin it.
