i have had my intake for about 3k miles now. the video is still uploading or being processed but i will have it up soon
and at the 5k mile service do they reflash the stock ECU or add upgrades? my car has been running sluggish after i had the 5k mile service. i have a GIAC chip also but i thing they might have got rid of it.
they will re-chip it but i will feel stupid if i still have it running and have them put it back on ya know? i wanna get a boost guage first so i can have physical evidence of my car running the higher PSI or not.
i actually got a new rim online... well it was used but its unbent now so the car doesnt shake. its great.
