I dont know if they do trials.. I think thats a REVO thing.... honestly if you want to make the power, and dont mind band aiding the problem the older GIAC code, with a MBC in parrallel is the way to go, it RIPS on 100 octane. if you want no headaches, and switch chip on the fly APR.. there race gas program is suppose to be good as well, but I havent had a chance to run it yet.
