Is this true?
Sorry, I missed this response.

No, it's not a bad idea. What your friend might be talking about is messing with the VE, and a speed-density system won't be aware of VE shifts. Using the combination of the MAP-based EMS and TVIS works fine and keeps you safe because if the TVIS is not functioning the way it should be, it will reduce your motor's VE, which will make you slightly richer. No biggie. Failure scenario is covered.

I have my TVIS in my car, which is EMS-powered using speed-density.
