It should be just fine. The only issue you may hit is boost going out of range a little if the new TMIC has less pressure drop. Seems you are on a stock turbo as well so I would say 99% chance you will be fine. Just make sure you put all the hoses back on properly and there are no leaks when your done. A lot of times its not the mods that create the problem its the install job.
If you need it to be checked out after the install my shop can review your tune and logs for free if you bring it out.
