The car could be trying to do a DPF regen but you may not be letting it finish if you only do town driving and don't keep the car above 2k rpm. The difference with the SRI and Ecoflex is the gearing. The Ecoflex is geared longer to assist with mpg especially on long journeys.
Siggys seem to be hit or miss when you begin talking about mpg. Mines was great to start then VX did software update and it all went tits up. From 37.5 average over 7 months to 28.4 after the update and they couldn't fix it.
As for DPF delete, it would fail an MOT if it was taken out. Plenty have had remaps but mostly for increased power.
