B.P.L.
I recently posted about a problem with my GU. It loses a bit of power (about 10-15%) shortly after the turbo has wound up after each gear change, and then comes back on around 2500rpm. It feels like the computer is telling the turbo to reduce psi for some reaon after boost comes on.
I have spoken to Nissan and now have a new computer and new air flow meter. Still not fixed.
Any other ideas out there?

The ECU (computer) has already been replaced.

I have heard that software change (ECU) has fixed this problem. Are you sure that Nissan replaced ECU with latest version? Should be a different part number to the one that was replaced.
Just a thought.
Regards,
Hugh

It is mine goessss great. Dont worry about warranty as it piggybacks on original ECU (velcroed on)so if you have trouble just change over plugs & pull it off.Regards Bob

BPL
If it still under warranty, don't do anything until Nissan fix the prob.
If not ECU, can only think of the air sensor to cause such a problem but I guess you've been down that path??
I suggest swapping the air sensor with another one from another vehicle which you know runs OK.....
cheers
