Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.

For B2B large customer orders, a "sampling + full inspection" dual regulation is adopted.

Our FOB vehicle quotes are typically valid for 72 hours (as domestic retail vehicle sources can be sold at any time); sea freight quotes are valid for 7 to 14 days (depending on shipping line changes). After expiration, prices need to be recalculated based on real-time exchange rates and domestic procurement conditions.
