Hey everyone!! I'm thinking of changing to a megasquirt plug and play PCM for my 2002 gt. Does anyone here use this item???? If you do, how do you like it??? What are the best features??? What are the limitations or problems??? The website highlights a number of features that I find appealing, including tuning while the engine is running.
I'd like to get some "real world" opinions before I buy, rather than just rely on manufacturer information/propaganda. here it is on the website:
