35thGT

i recently got a 99 35th ann. gt its had a few mods added to it and has been professionally dyno tuned, problem is i dont have the printouts from the dyno, i need to contact the previous owner soon. i was wondering what a rough estimate of my current hp is, i was guessing about 375? current mods are:

procharger@8psi
#42 injectors
bbk headers
x-pipe
flowmasters
sct xcaliber2 progammed
