So the SHO is the first car I have owned that I actually wanted to get a tune for. I chose AJPTurbo for all the great reviews on the site and I currently could not be happier. While running through the actual tune process was a little bit odd as my "your going to hit someone" LEDs flashed the whole time and the wipers ran the whole time, otherwise it wa a simple process. So far on my very minor spirited drive yesterday the thing pulls hard, real hard. It is a stock car 93 octane 3bar tune. I cannot wait to actually do the two data log pulls that brad wants to see if we can push it a little further. If your looking for a great tune and ease of logging I would recommend going with the SCT X4 and AJPTurbo. Oh and his business cards look epic as well.
