Hi there.
So im working on tuning my 2g with a remote tuner from here, and im having an issue where under load, my TPS is bouncing around under WOT from 94%-98%. The TPS is scaled correctly, and it reads 100% before it hits boost. Any ideas on how to fix this? I can upload a log if needed!

Thanks

Check and make sure there's nothing under the pedal that may be causing issues.
Check that the TPS connector is tight on the sensor and will not wiggle.
Check that the TPS is bolted down tightly.
Check that the throttle cable it bolted down tightly to the intake manifold.

I can't imagine that a TPS issue such as that would be a tuning issue.
 
Assuming the connector is tight and the wiring is not cracking, I'd be concerned that the 5v output from the ECU is flaking out.

There's nothing that could cause a tune to make it fluctuate.
