Ill give you an answer as straight and honest as its going to get. I have both Erics and Matts tunes loaded on my sct. Matts race file, its a 2.0ms tune, and erics extreme x, havent checked max pulse width on this file yet. But both files hold 3800 psi ICP, enough to keep the stock pump healthy and still make power. This will be taken care of shortly to maintain 2.2ms and 4k psi icp. But besides the point...
With my stock ARZ2AH10 inductive heating ficm calibration, Matts tune was far stronger in the 0-75% throttle position, but hazed a little more from 20-50% throttle. The strength of the file is worth it daily driving in the hilly terrain I currently live in, because it didnt haze all that much more and the power was more important. However erics tune definitely spooled the charger faster but the lack of fueling was limiting the balls it had.
However with Erics FICM tuning both files came to life considerably. FICM tuning with larger injectors and custom setups is honestly just as important as the ecm tuning. I still prefer Matts tuning just because of my driving habits and the roads I daily drive on. I still love erics tuning and after getting the shifting figured out its great, and spools the charger fastest in my opinion, but it isnt everything. Both make similar power, so its really up to driving habit and personal preference.
