Engine bogging down with any swift throttle change

It's odd that it'll affect the RTEK...
The stock ECU uses on open-loop process for idle, so I would think it would ignore the boost sensor signal.

I've gutted the stock ECU a long time ago and have been running a Haltech E8 for years now.

That's true, what I meant to say was that the MAP sensor readings we saw in the Rtek logs were noisy even at idle; idle itself was smooth and steady. When doing the baseline dyno pulls, we couldn't get consistent HP & torque numbers from pull to pull, so after checking the logs, it became obvious that the noisy MAP sensor readings was the cause, and the restrictor pill solved that problem.
