Ok im getting a little frustrated with how my truck is performing at the race track! The best i have been able to get out of it was a 14.7 @ 94.98MPH. I have an 05' VHO with a Trailblazer converter, Comp Cam, Nelson Tune, CAI, T-Stat, and true dual exhaust. My truck is gutless out of the hole! Like no tires spinning 2.6 60'! once it gets above 2500 it screams all the way to 6300 and hits second and bogs for about a second and then screams all the way to 95mph and im done racing. And im still in second gear at the finish line! I tried stalling my truck thinking that the computer was getting KR, so i tried just punching it! and still getting same damn results a little better just punching it though!

I know the Factory 20's and 31.8" tall tires have a bunch to do with my problem so im asking yall, The experts at all this stuff what it is going to take to get my truck in the 12's N/A?

Would some 4.10 gears, Pace setter LT's, Shift kit and servo, and some 27" tall drag slicks be enough?

If not what do yall think it will be good for? A mid 13? high 13?

Im probably going to end up blowing the G80 up with some big slicks so what size slicks would everyone recommend that would keep me from gutting the diff?

What will it take to get me in the 12's N/A? heads? bigger cubes?

Im out of ideas and need solid answers, any help would be appreciated.
