Wonder what my volumetric efficiency is like with the hybrid.  We shall see.  It feels quick now at 2.0 bar I know that.  Butt dyno says about 250hp.

Me too. To calculate you need a MAF sensor to take a group 3 log. Diagnostic limit then needs raising so you can read above 1249mg/stroke. Also need a group 11 boost log.

Oh the stock MAF craps out at 195 grams/second which is done running 1.85bar of boost on Alex's

Considering I've been running at 2.45bar in the mid-range, how have my injectors been coping John?!

I'm happy at the moment

Yeah. can't do the MAF thing I think  Thinking about how I can actually remove it entirely to be honest.

I must have freak injectors as well as clutch then!!

My duty cycle is about 72% at 4000rpm (+/- 2 %) which is apparently bang on.  Not bad considering it was set up using a vacuum gauge at a suggested level.  Only the stopscrew has needed winding out about 225 degrees to encourage earlier boost.  It might still need bringing out more.

Who says 70-80% is correct for a Gtb on a 1.9PD though

I was told 70% at 4000 was the aim.
