We use Hp tuners And my buddy has tuned his truck to well over 700 at the wheels with plenty more left in it. His name is QUIK on here and could help you out with any tuneing you need.
finally bought hp tuners and man its cool. i didnt even consider the entertainment value of looking at other peoples tunes and logs.yeah i got my segment swapped for 4l80e and applied my 2 bar speed density tune(on bench test) more pics this weekend. i passed on truck header for pass side and built a stainless log. pics coming.
