Camaro 2018 2SS AT Europe Version - Tune

[SlyStyle Performance]

Hi everyone,

I am from Germany and have a question to the experts among you.

I have a 2018 Camaro 2 SS EU version AT.

I have the Rotofab wet CAI with Soundtube, ported Stock Throttlebody and OCC. For this I already have a tune from a tuner from Germany on it.

Now I have 2 inch headers with 200er Euro6 HJS Kats installed. (2. cats delete too) & the mishimoto racing thermostat 160 F.

What i have to change for the headers???

[zr1driver]

any DTC set? maybe a broken spark plug isolator from header installation?

mit long tubes stimmen die laufzeiten f?r die o2 sonden z.b. nicht mehr.
