no no no no...SOME parts you may change will be tuned out, this is the biggest missconception on this forum that limits so many people from modifying this car.
I have tested this over and over and over.
the thread got deleted by the new admin but i will start a new thread just about the results of the header and not for retail purposes.
the summary of the test was this:
dyno stock
installed header
dyno'd with WR header
dyno'd with WR header 2k miles later (i think it was about 2k John ?)
dyno'd again a few months later
results:~9whp gain from stock after 3 months on stock ecu in a daily driver with plenty of miles on it and NO CELS.... THE POWER WILL STAY!!!!
