I just got my ECU back from Mario. All I can say is WHOA. This thing will ever more fly! I have never seen the kind of gains from a tune and I've tuned both my GTO and Tahoe previously. I would HIGHLY recommend getting Mario to tune your ECU. I haven't even put the dp, plugs or CAI (which there are no gains according to Mario just sound) and I'm supremely impressed. Well worth the money. Thanks Mario.
