I was skeptical to buy a used AP, but new from Cobb is $700+. This AP arrived 2 days early. Looked brand new and immediately checked to make sure it was in “install” state. Took less than 2 mins to install and retune Stage 2 base map. I was also happy that all related maps for my car were already on AP instead of having to download each one separately from Cobb website. I already have gauges, but I’ll leave it on windshield mount for easy access. Saved me almost $200. Highly recommend.
