So i got my car with a microtech ecu and it runs the car great. The only problem i have with it is i couldnt tune the thing for the life of me. As a miata guy i have built and tuned a few MS ecu with great susses my last miata made 350whp on 20psi with a evo3 16g.

So the question is should i sell my microtech lt10s and build a ms3 for the car or keep the microtech and pay some one 500 bucks every time i need it tuned.
