Having all the attributes that make a daily driven vehicle usable makes you think it's a watered down track car. But when you plant your right food down on the accelerator, an unexpected urgency rushes you forward like no other road car. No drama, just pure acceleration. Having this unparalleled performance lurking beneath the sensual body lines is beyond intoxicating. However, there is always room for more.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\"The car is already fast enough\". As true as that may be, we cater to the clientele that thinks otherwise. Truly experience the capabilities of your 675LT today with our ECU Calibration.\u003c\/p\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003e \u003c\/strong\u003e\u003cstrong

engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change.  Actual gains are dependent on the following:\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.weistec.com\/media-events-press\/crankvswheelhp\/\"\u003eLearn More about Crank HP Vs Wheel HP\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eModel – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series.  Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp.  Naturally the C63 will show more gains as it starts at a lower level.\u003c\/p\u003e\n\u003cp\u003eModel Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power.  The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.\u003c\/p\u003e\n\u003cp\u003eFuel – Fuel quality is HIGHLY important with performance vehicles.  Low quality and\/or low octane fuel will greatly impact engine output and potentially even engine health.  Top tier brand premium fuels should always be used to achieve the best results possible.\u003c\/p\u003e\n\u003cp\u003eDrivetrain – All wheel drive has higher drivetrain losses than rear wheel drive.  This results in lower numbers when testing on a chassis dyno.  Wheel\/tire size and weight will also impact chassis dyno results\u003c\/p\u003e\n\u003cp\u003eWeather\/Conditions – Temperature, humidity, altitude, and air density all impact engine performance.  Heat, high humidity, and thin air will all work towards reducing engine output\u003c\/p\u003e\n\u003cp\u003eEngine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output.  Properly maintained engines will have better performance than abused or neglected engines.\u003c\/p\u003e\n\u003cp\u003eSupporting modifications – The highest power levels require supporting modifications.  Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003c\/div\u003e","brand":"Weistec","offers":[{"title":"Stage
