The car takes a couple seconds for the boost to build like that. Before when I had the mainscale set around -22.5 The spool up was a little quicker, but still a bit lean, so now I'm either going to change my high,mid,low settings or figure out how to add a little fuel without changing the settings too much.

Not sure why you would set the mainscale so rich...I have my mainscale at -36 with 560cc injectors....which is exactly what you would expect doing the correction math....from there I just fine tune by rpm, but you can also fine tune with "MAF" load, which I have experimented with a little, but with no way to log MAF load, have decided to just tune AFC style by rpm,....I can def. see the advantage to logging MAF load, because then youd have a truer sense of where to tune....I generally end up fatting up fuel at the mid-range (2800-4200 area)...but not by much, maybe - 3 or so %...I let the LC-1 control WOT with the AF correction feature. I have not got that portion dialed in perfect yet, but it works pretty well.....if you use it, there is a gain adjust ment, as well as min/max correction factors that def. come into play....I found I had to turn the gain up to around 10 or so, and turn my max "lean" correction up to about 8-10% also to get it to lean out enough, and consistantly...thats what Im still working on, as I am still a little rich WOT...I also have timing control via Apex ITC (something everyone should consider - timing control that is...) I def. use the ITC too...
