I ordered the Thundermax Saturday night and it got here Wednesday evening. It took me about 3 hours to put it on my '07 Deuce. I don't really have a lot of mods on it, but was pretty unhappy with all the heat since HD flashed the ECM last July. It came with the base map already loaded, so set up was pretty quick. I only have about 40 miles on so I can't say much about it other than it pulls stronger in the gears and runs pretty cool. I put a thermometer in the oil tank last weekend and can see about a 10-15 degree drop there. It is pretty slick and I really like being able to see what the heck the engine is doing. I know a lot of you have these.I will post more when I run the thing a little longer. Ken
