I have said this before but it applies here. How involved do YOU want to be in the tuning process? Do you want to obtain a base tune, datalog it, send info to the tuner, have the tune tweaked and sent back to you.....perhaps several times....or do you want a plug & play tune that requires no effort on your part? If you choose the datalogging/tweaking route, do you want the tuner to explain exactly what he is seeing and what he is doing or do you just want to accept what he does with little or no dialog?
LMS is basically plug & play....easy peasy and very effective. You would get a substantial power boost and a safe tune for daily driving or occasional drag strip use. AJPturbo will want to see datalogs and tweak the tune to your specific car. Along the way, he will explain what he sees in the logs, what he is doing and what to expect. It is not just an excellent tune but also a learning process for you. It will also be very potent and very safe for however your drive the car.
I have used both LMS and AJPturbo and highly recommend either one depending upon which process YOU prefer. I have no first hand experience with the others.
