Ive now got the gearbox in the Scoob and its on the road, I stuck a boost gauge on it last night to see what kind of boost its running and its peaking at 15 and dropping back to 13 and holding strong. It has a ZD ecu and the only mods I know about is a full stainless and an induction kit. I was looking to see what boost it should be running as std and found this.

UK/Aus/Euro ECU's V7, 7D and 6D - 11.47psi, dropping to 9.47psi at 6600rpm. With Fuel-cut @ 14.87psi

There is no fuel cut or DET, the engine runs sweet as a nut. It was said on here a few weeks ago that my car would be about 225 bhp and I thought that it felt like it had way more than this, I rekon this explains why but Im thinking that the boost gauge maybe isnt tottaly acurate and is maybe reading 1 psi on the high side. Does anyone know if the fuel cut setting in the ecu is acurate.

 

i take it you mean its a 7D ecu?
open it up to see if its got a chip or a scoobyecu inside

Full decat may cause it to spike higher along with the induction kit. This may also cause it to run about 1psi above the stock 11.47psi.

It should fuel-cut at about 14.5psi, so I expect your gauge is reading a little high which is quite normal/possible.
