i had my car dynod a few weeks ago and i feel it was pretty low. 422hp and 422 tq. this was on a dyno jet with a 2.8 upper and a upr cold air kit. so i broke down and bought a ported stock t/b and plenum, o/r x, and a mac 3" catback. do you think the new mods will get me to the 450 marks? or do i have a dog? the tune is from rwtd and it was running 11.4 air to fuel, so i had a retune to lean it out a bit as well. thanks for the help.
