i currently have a 2007 lbz with 75k miles and it came with an Edge Tuner on it, I removed it and now have EFI live with the DSP5 switch. I have the insight cts2 monitor unit and was wondering how accurate the gauges are. been monitoring boost levels and can only get 20-22lbs, it does have EGR blocker plate also. Feels a little sluggish possibly boost leak. still need to check out.
