you will probably want to try and find lower psi wastegate springs to give your trans any chance of surviving, i dont know how the xp works with a turbo but with the st5 cam 130# springs and a double roller everything else stock that kit made 522whp on 16lbs of boost, the wastegate spring with the tention nut tightened down like i had it should put it around 10.5 psi and probably 400+whp your trans will not enjoy that, my best advise is just dont even try to use first gear it will just spin and if it ever does grab it will snap the input shaft
