i have a microtech, it depends on what you order. you get the ecu and a short loom about 20cm of wiring, the lt series are laptop tunable but you need to buy a laptop adapter. you can also get a hand controller for your dash or glove box so you can tune on the run. they come with an inbuilt map sensor that works to i thing 15psi but this is upgradeable. i am not really sure about how they compare to other brands but i suppose it depends who you ask. the rx7 and et/exa pulsar crowds love them.
