ive been doing some reaserch on unitronics stage 2 chip. my car is already set up for the chip having a 3" neuspeed dp and catback, forge 007 dv, cold air intake and fmic. there site says it will be running 20 psi. will i need to change anything else to support this? ive heard people say they needed to change their coil packs. and will it cause damage or break any of the axles or driveshaft.
if theres anything else i need or should have to run this let me know.
