OK. I fitted the SEM this morning with the 70mm throttle body and adapter plate. I spread a thin layer of gasket compound on the phenolic spacer to ensure a good seal with the gaskets. All fitted I did a TBA and adjusted the fuelling in Unisettings. With that all done I went for a long run, lasting around 1 hour covering varying roads - slow town roads, motorway and fast winding country roads.
I'm delighted to say the car runs superb, no problems at all, great throttle response, good vacuum, full boost, no big delay in revs dropping between gear changes and great top end, pulls nice and hard! Idle feels normal too. On cold start the revs did rise a little but nothing like with the 80mm TB.
When I came back I plugged my laptop back in to check for fault codes ...
NONE! Checked the fuelling and it's fine too.
Overall I am very happy with the SEM now, it's running superb with the 70mm TB and I am more than happy to keep it on the car. I apologise to Issam and Don for losing my patience at times, but it's all sorted now, many thanks for sticking with it and getting the parts to me.
Roll on a bigger turbo now!!!
