No, probably if your tuner did. Take it to some workshops down slater parage, or bresciani racing. They love them and have very fast circuit/street cars with them.
Whats bad about there tunning maps? I have seen a microtech run like standard.. anyway.... arguements you have no proof.
Do it, lots better then a crappy remap which you CANNOT SELL DOWN THE TRACK >
Atleast someone will buy your LTX8s when you want to sell it... whos gunna pay 600$ for a remap? there worth around 200$
Cheers
