I don’t think it’s wise to just go with the tune with the biggest numbers. What does a tune like that do to reliability, plug life, and potential knock conditions on readily available gas? If course it depends on your priorities and whether it’s for racing or street but it’s probably smarter to get a tune that’s a balance of performance gains without pushing the timing to the point where serious knock is a concern if your plugs aren’t brand new.

I’m not trying to rain on your parade, just don’t be suckered in by big marketing numbers, or even a nice dyno chart. No gains are had for free... there are trade-offs. MBs stock tune is way conservative, but just be concious of the fact that 200HP and 250Ft-Lb of torque just aren’t coming along for $1400 without any compromises in other areas. Read up on spark plugs for these tunes at the very least. Most of the major tuners talk a lot about crazy HP and torque gains but not what they do to your engine to achieve it. Read up on it and decide what mix of power and added maintenance or repair is ideal for you.
