My car there, the kit has been solid, the port injection only works when you need more fuel.
Cost-effective and you can run ethanol, tho the downside right now is that there is no flex fuel support. Really hope Cobb will add that in the future.
mine had this issue, likely it was from the floating disk. Took the wheel off, properly clean the contact surface and the noise is now gone, try that first maybe
Mine started having clunking noise as well, very subtle but very annoying.
Sounds like suspension is loose, tho doesn't feel like it.
Every time the front passenger side wheel hits a bump at low speed I got the noise coming from front driver side.
