Um. How are they doing that? Are they sending you an entire ECM? Then you send yours back? Because that’s what would have to happen.
I think you’ve been scammed.
Well guys finally got the VZ SS 5.7 running smoothly & just finished the mail order PCM mafless tune, so I had a few issues and nothing to do with the pcm I picked her up from the garage this morning stock except 1-4 1-5/8 headers, high flow cat's took her for a drive & to be honest felt sluggish , so I decided to install the aluminium VCM OTR mafless & turbo industries mafless tuned pcm , she not sluggish anymore , throttle is more responsive, smoother gear changes I obviously abide by the law so I didn't give her a boot yet but probably get thrown back in the seat a little more lol but yes half hour install for OTR & PCM, pcm will be sent back to turbo industries for the deposit back $250 .
