Wow this is a great topic. I am so confused about this entire tune/tuner thing. So forgive me. This is how I understand it. We who purchased 2011 mustangs can now order an SCT SF3 tuner which comes preloaded with a dyno tune to include the addition of the Steeda CAI added for roughly $380.
Now somewhere along the line Jon Lund who seems to do special tunes for Lethal Performance,Evolution Performance and ???? If I can make another 44HP and 52ft/lbs of torque for $380 + CAI does that mean for $480 + cost of CAI I will get another 10-15 HP with a John Lund tune? Now don't get me wrong I'm not trying to be a smart a$$ or piss anyone off, I'm just trying to spend money wisely by being informed. I assume a Jon lund tune would include mods like Cat back,X-pipe,octane. This is a quote from Lethal Performance website.
