I don't know I would call them gimmicks, but I agree that if you want the full potential of what the ECU can do, it will require a new mapping table uploaded into the ECM with the ability to also modify the TCM. For 1/4 the cost, to get an additional 90hp and 150 lb-ft or torque, it's not a poor investment at all as long as it doesn't constantly want to regen which is what I am looking into now. By having my iDash, I am already monitoring boost and EGT on my main page song with regen status and DPF stats.
