This inline module plugs directly into your truck's computer system, letting you sharpen throttle response, recalibrate for larger tires, or adjust your gear ratio in a matter of seconds. Guys running bigger tires know the frustration of a speedometer that's suddenly off and a transmission that shifts at the wrong times, and the Pulsar LT fixes that without requiring a full tune. It also gives you the option to disable Active Fuel Management or Dynamic Fuel Management, which is a big deal for owners who've dealt with lifter tick or rough running cylinder deactivation on the 5.3L and 6.2L engines. Because the Pulsar LT works as a plug-and-play device rather than reflashing your ECM, your factory warranty stays intact, which is a real advantage over a full aftermarket tune. Whether you're setting up for towing, dialing in a lifted truck on 35s, or just want throttle response that doesn't feel lazy off the line, this module puts that adjustment in your hands. It's the kind of upgrade you install once and then quietly enjoy every time you drive.\u003c\/p\u003e\n\u003ch4\u003eInline Control Built Around Late Model GM Calibration Systems\u003c\/h4\u003e\n\u003cp\u003eThe Edge 22451 Pulsar LT is an inline control module engineered specifically for 2019-2022 GM Silverado and Sierra 1500 trucks. Rather than modifying the ECM directly, the device sits inline within the vehicle's computer system, giving it the ability to adjust throttle mapping, recalibrate tire size across a 29 to 50.9 inch range, and modify gear ratio settings from 2.00 to 6.99 without permanent changes to the factory calibration. It also allows drivers to toggle Auto Start\/Stop, disable AFM or DFM cylinder deactivation, adjust the top speed limiter between 82 and 140 MPH, reprogram TPMS pressure thresholds, and clear diagnostic trouble codes on demand. One important compatibility note applies to 2022 model year trucks specifically. Refreshed 2022 models are not supported, and owners can confirm which version they have by checking the 12th digit of their VIN, where a 4 or lower is supported and a 5 or higher is not. It's also worth noting that if ring and pinion gears are physically changed, GM's factory calibration disables cruise control at that point, and while the Pulsar LT can recalibrate the speedometer for the new gear ratio, it cannot reactivate cruise control or clear related codes, since that requires full ECM and TCM tuning. According to the manufacturer, this product is legal under the EPA's Tampering Policy dated November 23, 2020, based on their own test results, though it is not legal for sale or use in the state of California pending CARB certification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2019, 2020, 2021, 2022 GM Silverado\/Sierra 1500 \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNot compatible with refreshed 2022 models, verify 12th VIN digit is 4 or lower\u003c\/li\u003e\n\u003cli\u003eNot legal for sale or use in the state of California\u003c\/li\u003e\n\u003cli\u003eManufacturer states legal under EPA Tampering Policy dated November 23, 2020 for other states\u003c\/li\u003e\n\u003cli\u003eCARB certification testing is pending, product is not currently 50-state legal\u003c\/li\u003e\n\u003cli\u003eDoes not modify the ECM, factory warranty remains intact\u003c\/li\u003e\n\u003cli\u003eChanging physical gear ratio disables factory cruise control per GM calibration\u003c\/li\u003e\n\u003cli\u003ePulsar LT can recalibrate speedometer but cannot reactivate disabled cruise control\u003c\/li\u003e\n\u003cli\u003eFull ECM\/TCM tuning required to correct cruise control or related codes\u003c\/li\u003e\n\u003cli\u003eInstruction manual and software included\u003c\/li\u003e\n\u003cli\u003eCalifornia Proposition 65 warning applies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/documents.rangetechnology.com\/406701bf15566869b56ee893e38dbea3216e441d.pdf\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Range Technology","offers":[{"title":"Default Title","offer_id":49526955180316,"sku":"RNG22451","price":649.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/c07a5f717c42bb169cfe6fe1f53ff5a3adc9c9f9.avif?v=1788989996","url":"https:\/\/www.alligatorperformance.com\/products\/range-22451-pulsar-lt-control-module-19-22-gm-sierra-silverado-1500-gas","provider":"Alligator Performance","version":"1.0","type":"link"}
