Good news bad news

Bad news is I went to take off my drag radials tonight and they were down to the core guess that explains part of my traction issues and why I hardly had any rubber on my fenders, the only bummer is now i've got to cough up another 340 bucks or so for some new ones before I can race again.The good news is I put my new BFG street tires on today and they fit, barely but they fit.On my 18 by 10.5s rims they measure in at 12inches.Not as beafy as Bills but they look pretty sweet.I also was checking out my dyno graph to see if I was missing the sweet spots in my shifts to try and help my trap speeds because dont think my traction issues hurt me to much except for my times maybe, sure felt a little slick, though anyway between 4500rpms and 5600rpms on my dyno graph I was pretty rich around 11.1 and then down to barely above 10 then from 5600 rpms and up to red line up to around 11.7 11.8.So I cant adjust it with my predator,it will only let me adjust the whole 4 to 7000 rpms not in between .I do beleive im in need of a custom predator tune.Hopefully that should do the trick and some practice
