Yeah, around 3k.

I bought mine last year, I think they had small increase after that. But in the end I think it is worth it, everything just plug in, battery and ignition wires on and you can start the engine. Wideband lambda and throttle included.

Surely they should put more thought to the sensor calibration and some stock base maps for spark and fuel. If the kit is specified for your engine, also values in ECM should meet the purpose of it.
