Anyone know of an ECU Tune or a Lowering Module for the Bentley V8?

Tune is available but you will have to remove the ECU and bench flash it. You can ship your ECU, have it tuned and get it shipped back to reinstall it. I'm not sure of anyone in the NYC area doing bench flashing anymore.

you can go the more cost effective route and use linkages or h&r makes a 100% plug and play module for it msrp $2100, although people have been buying them for around 1800. Renntech makes a module but its ntot 100% plug and play, you have to remove pins from the oem harness and insert them into the renntech plug before you plug everything together. i would assume APR's S8 tune would work on the bentley's, prob might want to call them and ask.

I got the H R Module its awesome - who bench flashes that ecu?

they dont list bentley but i would definitely try calling www.goapr.com and ask them if they can do the bentleys. they have tunes for the S6/7, S8 rs7 etc. it's essentially the same motor as the S8.

for the S8:

The APR Stage I ECU Upgrade gives you higher peak numbers of 647 HP/671 FT-LBS on 93 (R+M)/2 octane and up to 685 HP/679 FT-LBS on 100 (R+M)/2 octane race fuel. As much as +130 HP and +142 FT-LBS of torque are available through the power band! APR’s ECU Upgrade is the best power per dollar modification for the new 4.0 TFSI V8 and gives it just the extra edge these cars lack from the factory without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent car.

Do you have more information on the tune? I spoke to APR about their tune, but they informed me they've only released it for the Audi models.
