I just bought a 02 'L, Black of course, I tried to get a True Blue one but these fools down here in Texas wanted 900. more cause they got it From Colorado???:rollseyes: Anyway my question is, this truck came from Utah and has the High Alttiude Pkg? Does anyone know if and what this does to the performance? I can tell you this the truck is boosting to 9 to 10 psi of BOOST right before shifts and it really hauls ass for being stock. I bought a K&N airfilter for the stock box and pulled the fender elbow and now it is showing over 10psi of BOOST, I am thinking around 11 or 12 psi
This truck hauls ass, does anyone have any info on the High Altitude pkg? Henry...
