Hello David,

'Or at least include that info in your post. I assume you have a 1990-1993 300D 2.5 Turbo though.'

You are right. 1991 year. I have the model in my description though.

'2) You cannot simply disconnect the EGR on the 90-up engines. The EDS will know you killed it, and will prevent boost from building by keeping the wastegate open.'

The interesting thing is having the valve disconnected the car felt more responsive.

'5) You need to test your car from 0-60mph with a stopwatch on flat road. It should be about 11-12 seconds. If not, you're down on power, and probably need to either reconnect the EGR, or disable it correctly as mentioned in item #2 above.'

I already reconnected the EGR. As a matter of fact I can do the test today, just for the fun of it. Both with EGR valve disconnected and connected. Will post in a few hours.
