So, I bought an AO2B diff for my 1994 Jspec TT auto about 8 months ago.
I had it fitted last week, and I had my old AO2A open diff removed.
Previously with the old open diff, when the car was in Manu mode and doing 60mph, I would select 2nd gear and the revs would sit at 4k rpm. Just a nice sweet spot for both turbos to be on spool and give a good pull in acceleration.
So I tried this the other day when driving home after having the new diff fitted, Manu mode, 2nd gear at 60mph and the revs shot up to 5k rpm.
Strange I thought. So I slowed down and matched my revs to 4k rpm and the speed now showing was 50mph.
So....the question is....
Have I been sold maybe an AO1B instead of an AO2B or is it an AO2B but I need to change my speed sensor what with changing the diff from an open to a lsd?
Any help much appreciated.
Thanks.
