The car is being dyno'd with an 80's posche specialist he has got the correct test gauges and equipment. He is going to get 2 boses welded in to the headers to fit wide band lambdas, also we will be able to check ignition timing under load. You never know it may just be a rattle, I think it is probably not though so a dyno test is a good idea. I will also get to know how much of an increase over 320hp the mild mods have gained.

I am still thinking there is a fuelling issue leaning out from 4.5k (when the noise starts) and I am unsure about the WUR and valve, the car hangs on revs and has intermitent idle speed.

A point about the O2 sensor, I understood it was an improvement over the 930 system richening the fuelling on full throttle by lowering the fuel pressure, why would I want to remove it?

Thanks again for all your input guys
