I was wondering what tools are required to sync up throttle bodies from a vacuum perspective, how do you actually do it.

I purchased a set of MRPs AT Power ITBs so wondering how to do it. Thank you!

I'd assume the directions that come with the kit should tell you how to set them up. If not, ask Barry @ MRP

As to the tool you use to measure the air flow... there are a couple of designs...



and....





essentially you put these over the opening and measure the air flow, and make the adjustment to balance the air flow

You definitely need a tool to measure the air flow as shown by OST
The important thing is to adjust the linkage off of idle.
A way to do this is to open the throttle a small set amount, this can be done by wedging the cable open. Then you need to adjust the linkages so that each itb reads the same. The tricky thing is then having enough adjustment so that you can get it to idle once all are closed. Some trial and error will be required.

If the AT Power throttles are "delivered fully assembled" as they state in their literature,
the throttle stops and linkages should be factory set, and not require calibration. If this is
correct, then I would strongly advise against dismantling them or interfering with the
adjustment in any way. It can be a frustrating job calibrating them without the correct
equipment, and one best avoided if possible

GREAT point!!!

Required? None, except a piece of tubing, mechanic's stethoscope or one of those tube type airline headphones and halfway decent hearing in one ear. Listening to the hiss at the same position on each one will easily get you within those marks on the Unisyn's scale. IDK about the sensitivity of the German thingy.

Also, Any & all advertising claims are highly suspect, especially automotive aftermarket stuff.
Good luck.
