Mechanical issues, connection problems, incomplete hardware, or incorrect fuel can consume the purchased time and may prevent completion. Work beyond the included block must be purchased through the Additional Calibration Time product and scheduled before more tuning continues. New turbos, injectors, fuel systems, fuels, engine combinations, or other major hardware changes may require additional time or a new tune.\u003c\/p\u003e\n\u003cp\u003eSpecific power is never guaranteed. Results depend on vehicle condition, hardware, fuel quality, environment, and safe operating limits. The customer is responsible for legal and emissions compliance; Undisputed will not calibrate public-road vehicles to defeat required emissions or safety systems.\u003c\/p\u003e","brand":"Undisputed Racing","offers":[{"title":"Naturally Aspirated","offer_id":55510307438891,"sku":"UND-N51N52-NA","price":299.99,"currency_code":"USD","in_stock":true},{"title":"Forced Induction","offer_id":55510307471659,"sku":"UND-N51N52-FI","price":499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/8574\/4427\/files\/undisputed-n51-n52-custom-tune-box.png?v=1788965275","url":"https:\/\/undisputedracing.com\/products\/bmw-n51-n52-custom-tuning-msv70-msv80","provider":"Undisputed Racing","version":"1.0","type":"link"}
