Question about going from HEX stage 1 to 2 and installing mods

momentumraces · 12-14-2018, 01:20 AM

I currently have no bolt on's installed on my car, just a stage 1 HEX tune. When I had the initial read done to be sent to VF, the shop owner told me that it wouldn't do me any good to do a cold air intake and that sometimes they would cause issues with HEX tune.

So first question is there truth to this? I really want a CAI.

Second, I plan to upgrade to stage 2 and install a fabspeed sportcat here in the next month,then before it gets too hot, do the CSF intercooler in the spring and possibly some other bolt on's like a charge pipe. Will the HEX tune adapt to these bolt on's on it's own?

Intake will provide negligible power gains but totally worth it for the sound. Just be careful which one you buy since some will trigger the CEL
