I happen to be a Torco advocate and I appreciate the OP posting this. I dont remember paying much more than 150 for a 5 gallon drum but I will contact bret and see what he can do for me. Any way I have a Torco map (32oz per tank) and have a 91 octane map. Here is the comparison, major improvement with the torco map as you can see. I love the stuff.. first is the 91 map. both tunes were done on the same day with the same mods.
