Default Net torque seems low...

So I just took my 225 TT with mbc set to 15 psi and logged my net torque. The highest value I got throughout the third gear pull was 164.8 N/m. When I convert that to lbs/ft I get 121.6. Seeing as the stock 225 came with 207 lbs/ft(maybe??) I'm somewhat confused. Is the low torque reading accounted for by quattro driveline loses or is something amis?

is that the diff between crank and wheel? if its supposed to be 207 crank w~20-25% quattro drivetrain loss, then the # sounds about right.

A twenty-five percent loss would leave you with about 155 lbs/ft of torque. My loss would be about fourty-five percent. Abnormal?

I've noticed that starting around 2600 rpm I get 3 degrees of timing pull(if that is what block 20 is telling me) which increases up to 11 degrees of timing pull at 600 rpm. From what I understand I shouldn't be seeing numbers like that! What could cause this?

I had a diode in but the boost was still only set at 15 psi. So I put everything back to stock and am now getting 8 degrees of pull in the upper rev range. That still seems fairly aggressive for stock.

Could be the heat or gas. But you are low and that probably is the cause
