They then proceeded to the dyno where significant gains were measured particularly in the torque mid-range area.

Then I read in this thread that many users are tuning with 3rd party software and I am asking why they do so. The easy answer could be that they are in search of further gains but is this really the case?

One of the many reasons why this product is attractive to me is the mid-range torque increase without the need for tuning.

Please explain.

While the ECU can learn and adapt, Custom e-tunes are still the way to go for best overall drive ability, safety(Not running to lean or to rich) and power/smoothness. I am going through the same with @Tor who is helping me dial in my car(UEL Tomei catless Header). I am going to have him add a bit of margin into the tune to insure Advance Multiplier is always at 1 and my AFR's are inline everywhere and not just at WOT, insure I have maximum timing added in all areas. I want to be able to take the car to the track beat on it and not worry about the engine running lean under even higher stress.
