[928uk] Fwd: Scary bits and a great map

Mon Feb 27 21:58:03 UTC 2012

Must admit I haven't checked the pressures but I'm positive the spacers are the issue.
I'll report back on Sunday or so.

I think you will find that with the Pklamp, the flexplate loading will be very low.  When loaded you will see the arms of the flexplate bending, and the coupler will spring back a few mm.

Now that is a little out of spec according to one of those articles you kindly sent me but significantly less than the 0.4mm suggested to imply TBF.

>> Regarding the mpg disbelief, I simply read what the computer told me.  Rob said he could reach 27mpg cruising at 65.  I was cruising at 72.  I will manually check though, using the trip counter and a calculator.  If it is correct, it is certainly better than normal and must be a great advert for that engine management remap.
