The temp sensors aren't different between turbo and non-turbo, but yours could be acting up. The E39A VR4 ECU and MAF aren't calibrated for the 510cc injectors, so that could be causing an issue as well. These cars had 450cc injectors. That would cause you to run a bit rich at idle and partial throttle. I'd recommend getting a S'AFC or something to tune out the difference in injector size.

Tony, didn't some GVR4's come with larger injectors and a 16g? I know the ones we got here in the states didn't but I'm pretty sure some did in other parts of the world.

Yes, if he has a GVR4 RS setup then it would come with the 510's and everything...those are kind of rare though, even overseas.
