This product is for those who already own the DS1 on the 2.5t or 4.0t and need to hire VLMspec to be their custom calibrator. This price includes all maps and fuel types for your setup. All tuning will be done by Jared Van Leuven


Stage 1-2 (stock turbo) vehicles are $750

Stage 3 (hybrid or big turbo) and up including built engine cars are $950


The DAZA DS1 product comes after the roaring success of their 4.0T product. They have incorporated all the same features, however they do not have OTS maps beyond stage 2.  VLMspec offers custom mapping for this product and any combination of hardware.
