When i push my R33 hard i notice the tacho dail 'ticks' up slowly, not smoothly, from low revs. The same thing happens to my boost gauge. I've noticed this about the same time as i've been losing boost pressure.
What causes this?
Thanks
Never thought of that one. I'll check that, cause i have a feeling its the turbo which is the problem and not the piping or hosing.
I'll take a look at the turbo and see if the gaskets are ok.
Thanks for the idea
