Welcome to the site. Getting to the high 12's low 13's is not that bad. Exhaust efi live or even a. ppe hot +2 race and just a transgo jr and converter upgrade will last a long time for you. I pushed that setup for a very long time when I first started playing around and had the most fun for the smallest bang for the buck.
Sweet thanks can't see the shift kit or converter being any different from the other truck
