hey i just picked up a 99 gtp 4door with some mods
after reading on here for a little im actually a little concerned of them lol
mods
headers
exhaust
cai
3" blower pulley
the cars feels pretty quik, but it sounds like theres a bad lifter cause i took the blower belt off and the noise is still there
i am not sure if there are any other mods cause i didnt take car apart yet lol, I bought it from an auction in jersey so there was no description of the mods
I think it prob has a 180 or 160 stat cause the temp stays around 180 while cruising, it might have a small cam cause the idle seems slightly rough ( not as smooth as a regular gtp would idle), and it is definately tuned because i pulled the tune with my hptuners and the secondary o2 is set to not report any faults..
I did a little datalogging and it made between 12-13psi boost at full throttle, and it showed up to 7.5* knock
so i know i have somethings to look at, but not sure if its setting the knock sensors off cause of the possible bad lifter
