Is there a place where I can get the tps to react to quicker. When I accelerate it has a hessitation? I have installed a tb which may be a little on the big side.

The speed at which the TB opens (react quicker) will not help your problem. A bigger TB will actually slow down the TPS reaction time.

When the ECM sees a voltage output from the TPS, it does calculations to add fuel as the blades open. If there is a bigger (52 mm) TB, then more air is available at a smaller TPS voltage, so there is more air, less volts, and less fuel. The linearity of the TPS volts vs Blade angle (air flow) has changed with the bigger TB.

A better way to correct the out of calibration, TPS volts vs air flow, is to tune (recalibrate) the ECM/Eprom to a more correct volts vs air flow.

Just changing the reaction time will not fix all areas (it would be a global type change) and may even cause trouble else where.

The acceleration enrichment (AE) is where the changes are made, amount and duration both will both need to be reset. Your power enrichment (PE) will also be leaned out, so that will need help too.

I'm running an a1 xdf and don't see where you can adjust the volts. Would adjusting the AE Async Pulse Multiplier Vs. Delta TPS Table work?

I am not educated about the A1, so I can't give detailed fixes.

I live in 6E arap land.
