I didn't really notice that much of a difference. I checked it before my tune and my boost psi was over the set mark. I did pop a CEL. Which my tuner said was caused by the new TMIC. It changes the boost drop rates, colder air charge temps, and the newer TMIC flows much better. So, it only makes sense.
The reflash was a new kick in the pants with the amount of TQ i'm putting down now. But, that was due to the other mods just as much as the TMIC.
