Well my buddy came over and checked over my system, said it all looked good. He told me I might not be able to tell much difference with a 75 shot. To be honest, he's right. It feels strong at WOT, but then it always does. Either it's not working or my butt dyno needs to be calibrated. I'm going to try it again tomorrow morning and try his tip: floor it with the system off and then flick it on. He said that I shouldn't bother with a 75 shot, I should go straight to 125. (Do we think alike or what?) I did notice that it seemed to pull better past 4k rpm. I'm anxious to hear scrming's report.
